Ultralight Dark Matter Background: Waking, Shaking, and Detecting Xucheng Gan, DESYEvent Type: Informal HEP Talk Date: Tuesday, October 20, 2026 Time: 11:00 AM - 12:00 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: Ultralight dark matter (ULDM) that induces variations in fundamental constants is well motivated by a variety of UV models and provides an excellent target for rapidly advancing precision measurements. While linear interactions have been extensively studied, quadratic scalar couplings remain much less constrained and arise naturally in many theories. Importantly, they can generate qualitatively new signatures through background-induced effects. In this talk, I will introduce two major classes of background-induced effects: wake-type forces and oscillatory-type forces.
For wake-type forces, I will present a complete framework that unifies previous approaches developed for different regions of parameter space. I will then apply this framework to the MICROSCOPE satellite, a leading space-based test of the equivalence principle. The Earth's screening effect redistributes the directional dark matter wind, while the satellite's orbital motion modulates the resulting signal, imprinting a characteristic frequency-band structure with an annual modulation that provides a distinctive fingerprint and substantially improves sensitivity. For oscillatory-type forces, I will discuss two distinct signatures in gravitational-wave observatories: a coherent signal at the second harmonic of the ULDM oscillation and a stochastic beat signal arising from interference among different ULDM modes. I will focus on pulsar timing arrays (PTAs), which currently provide leading sensitivity, and the future flagship space-based observatory, the Laser Interferometer Space Antenna (LISA), where screening is absent. Together, these two classes of background-induced effects provide complementary precision probes of quadratically coupled ultralight dark matter through late-Universe measurements.
The First Light from Stellar Explosions Udi Nakar, Tel Aviv UniversityEvent Type: Astro Seminar Date: Tuesday, October 20, 2026 Time: 2:00 PM - 3:15 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: A stellar explosion launches a radiation-mediated shock that propagates through the star and breaks out when the optical depth ahead of it becomes too low to sustain the shock. The photons released during shock breakout are the first electromagnetic signal from a cosmic explosion and carry unique information about the medium the shock emerges from, including its geometry, radius, composition, and density profile.
In this talk, I will discuss the distinctive properties of radiation-mediated shocks and describe the resulting breakout emission in a variety of cosmic explosions. I will highlight some of the things that observations of shock breakout and early emission have taught us so far, and some of what we expect to learn over the coming decade.

A Path to the Analytic Thermal Bootstrap Alessio Miscioscia, Stony BrookEvent Type: HEP Seminar Date: Wednesday, October 21, 2026 Time: 2:00 PM - 3:00 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: I will discuss how thermal data, especially thermal two-point functions, can be constrained by a combination of the KMS condition, analyticity, clustering, and the OPE. In particular, I will propose KMS-symmetric dispersion relations for two-point functions. Crucially, only operators contributing to the discontinuity appear in these formulas, and the blocks are explicitly KMS-symmetric, in analogy with Polyakov blocks at zero temperature. The price to pay is an unknown arc function, which can be completely determined using the remaining properties of correlation functions.
Owing to the manifest periodicity of the expansion, I will also discuss the momentum-space version of this construction, making its connection with quasinormal modes (QNMs) explicit. These equations provide a complete bootstrap problem for the QNMs. I will illustrate the framework with free, perturbative, and large-(N) examples, including holographic correlators, and mention applications to the 3D Ising model.

Towards Positivity Bounds for the Effective Field Theory of Inflation Matteo Delladio, ETH (Zurich)Event Type: Informal HEP Talk Date: Friday, October 23, 2026 Time: 3:00 PM - 4:00 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: Effective field theories with nonlinearly realised Lorentz symmetry arise broadly, from cosmology to condensed matter. Whether reliable and widely applicable positivity bounds can be derived for such theories remains an open question.
I will first review the obstacles faced by standard methods and discuss an alternative approach. I will then introduce an object with good analyticity properties whose high-energy behaviour can be controlled.
Finally, I will explain why, despite this, the construction does not generally yield positivity bounds and discuss a possible way forward.

Electromagnetic signatures of massive black hole binary mergers and their identification in multi-messenger observations Chengcheng Xin, Harvard University | Black Hole InitiativeEvent Type: Astro Seminar Date: Tuesday, November 3, 2026 Time: 2:00 PM - 3:00 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: Massive black hole binaries (MBHBs) are a natural outcome of galaxy mergers and are expected to be among the strongest sources of low-frequency gravitational waves. At sub-parsec separations, however, these binaries are extremely difficult to resolve directly. One promising approach is to search for their signatures in the time-domain variability of AGN lightcurves. Orbital motion can imprint periodic or evolving (“chirping”) signals in quasar light curves through mechanisms such as relativistic Doppler boosting. In this talk, I present a series of studies exploring methods for detecting compact SMBHBs in large optical surveys, building towards a systematic search. Using mock data motivated by the new time-domain survey LSST, we evaluate the performance of these methods. I will demonstrate that both periodic and chirping signals, consistent with GW-driven inspiral, can be identified in large optical surveys alone, and that these detections can be confirmed with even higher confidence when combined with GW observations. Finally, I will discuss a potential multi-wavelengths signature of MBHBs due to multiple disk- and jet- components.

Inference through Compression: Learning the Physics of Multicomponent Systems William Jacobs, Princeton UniversityEvent Type: Physics Dept Colloquium Date: Thursday, November 12, 2026 Time: 4:00 PM - 5:30 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: Physical understanding benefits from simplicity and interpretability, yet quantitative prediction in complex systems often demands much richer descriptions. In this talk, I will show how compression can be used to extract physical insights from systems in which the microscopic details still matter quantitatively. Using examples drawn from heteropolymers, biomolecular systems, and programmable soft matter, I will demonstrate that the thermodynamic structure of multicomponent systems can itself be compressed, so that molecules acquire low-dimensional representations through their interactions with other components. These representations retain the relevant physical information while enabling quantitatively accurate predictions of thermodynamic properties across a wide range of mixtures and conditions. By revealing which microscopic details control collective behavior, this approach provides a systematic route to infer effective variables, extrapolate to new systems and conditions, and rationally design multicomponent matter.
How Dust Evolution Shapes Protoplanetary Disks Thomas Pfeil, CCAEvent Type: Astro Seminar Date: Tuesday, November 17, 2026 Time: 2:00 PM - 3:15 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: " Planet formation begins with the coagulation of micrometer-sized dust grains in a protoplanetary disk. This particle growth not only provides the building material for planetesimals but also shapes the environments they form in.
Aerodynamic drag forces between gas and dust determine how fast the grains drift and how efficiently they can be trapped in the frequently observed rings and vortices in protoplanetary disks. The size of the particles thus affects the available dust mass and composition throughout the disk. Dust also dominates the opacities and therefore regulates the thermal structure and the onset of hydrodynamic instabilities that depend on thermal relaxation.
In my talk, I will present two recent applications of coupled multifluid simulations and dust coagulation models that capture the interplay of microphysics and large-scale dynamics in protoplanetary disks:
Our simulations of planet-disk systems with dust coagulation quantify the amount of small dust grains that diffuse and drift through planet-induced gaps. These calculations constrain the composition and available mass of solids in the inner disk regions.
We furthermore investigate the effects of dust evolution on protoplanetary disk turbulence, induced by the Vertical Shear Instability. Our simulations show that efficient dust coagulation can suppress turbulence in protoplanetary disks, due to the reduced collisional cooling in the dust-depleted upper layers.
Understanding how dust coagulation influences the dynamics of protoplanetary disks is thus key to understanding the initial conditions for planet formation and to interpreting multi-wavelength observations."

The Slow Creep of Glacial Ice: A Multiscale Disordered Material Justin Burton, Emory UniversityEvent Type: Physics Dept Colloquium Date: Thursday, November 19, 2026 Time: 4:00 PM - 5:30 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: One of the largest uncertainties for future predictions of sea level rise is the dynamic mass loss of ice into the ocean. Icebergs break off from ocean-terminating glaciers and form granular piles that jam up future calving events. In this iceberg purgatory, a floating granular mélange, forces are transmitted through contacts between individual icebergs 10-100 meters in size. Further upstream, before reaching the ocean, bulk glacial ice creeps slowly over time, behaving like a non-Newtonian liquid where the relationship between stress and deformation rate is a key factor for making predictions about the stability of ice shelves and ice sheets. Glacial ice is composed of polycrystalline grains that can be centimeters in size and form a disordered network of grain boundaries separating crystal orientation. Within each grain are disordered arrays of dislocations whose dynamics determine molecular-scale creep. Within this multiscale problem, I will primarily focus on the slow creep of glaciers, from molecules to grains. Recently we developed a physics-based rheological model that captures all three regimes of transient creep in polycrystalline ice under constant stress. The model replicates the minimum strain rate near 1% strain, which results from a competition of two timescales that depend on the driving stress. The model also exhibits apparent power-law exponents in the stress dependence of the strain-rate minimum, which is a quantity often reported in experimental data and directly used in large-scale climate models.
AI-Assisted Physics Research: Experiences and Caveats Xingyang Yu, FirstPrinciplesEvent Type: CCPP Brown Bag Date: Monday, November 23, 2026 Time: 12:30 PM - 1:30 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: In this talk, I will share my experiences of using AI in theoretical physics research. I will first discuss how the AI chatbox can help understand and push forward a project under human's control. Then, I will discuss how AI agents work, from giving them specific calculation tasks to asking them to explore a vague research idea. I will discuss some difficulties I encountered during this AI-assisted workflow. In particular, sometimes the agent moved away from the physical setting of the project, or continued developing an argument before I understood the previous steps. Based on these experiences, I will discuss how to better work with AI, check its results, and keep track of the direction of a research project. The focus will be on practical research experience rather than the technical details of AI, so no prior knowledge of AI is needed.
Gravitational-wave and electromagnetic signatures of binary black holes with circumbinary gas Zoltan Haiman, IST AustriaEvent Type: Astro Seminar Date: Tuesday, November 24, 2026 Time: 2:00 PM - 3:15 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: Binary black holes (BHBs) embedded in dense gas hold the promise of "multi-messenger astrophysics": when they are detected both through gravitational waves (GWs) and electromagnetic (EM) observations, they will enable novel science. This is true both for massive BHBs, whose GWs will be detectable by the future LISA satellite and by on-going pulsar timing arrays (PTAs), as well as for stellar-mass BHBs detected through ground-based GW detectors. In both cases, identifying coalescing binaries through their EM signatures will help clarify their astrophysical origin and yield novel probes of cosmology, fundamental physics, and accretion physics. In this talk, I will describe how circumbinary gas may impact the orbital evolution of binaries, while producing characteristic EM signatures for both massive and stellar-mass BHBs, based on hydrodynamical simulations and analytic models. In both cases, several binary candidates have been identified in optical surveys, and LSST should soon be able to uncover robust binaries based on their high-quality, multi-band light-curves.

Using Tidal Disruption Events as Probes of Massive Black Hole Formation and Growth Over Cosmic Time Suvi Gezari, University of MarylandEvent Type: Astro Seminar Date: Tuesday, December 1, 2026 Time: 2:00 PM - 3:15 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: The tidal disruption of a star that wanders too close to a central black hole is a unique probe of quiescent supermassive black holes lurking in the nuclei of galaxies. We have demonstrated the ability to discover and spectroscopically classify large samples of tidal disruption events (TDEs) in the optical from the Zwicky Transient Facility (ZTF) Northern Sky Survey, with systematic high-energy follow-up with Swift and XMM-Newton. From these efforts, we now know the spectroscopic signatures, multi-wavelength properties, and host galaxy preferences of TDEs, and can begin to use TDEs as powerful probes of massive black hole demographics in quiescent galaxies. One of the most exciting applications of TDEs is the ability to probe intermediate mass black holes (IMBHs) that are expected to reside in dwarf galaxies, with demographics that encode the seeding mechanism of massive black holes in the early Universe. I will outline our strategy in the next decade for searching for TDEs across the black hole mass function, and over cosmic time, by extending our sensitivity to TDEs to lower central black hole masses and higher redshifts, by exploiting the discovery power of the next generation of wide-field time domain surveys, including Rubin, Roman, ULTRASAT, and UVEX.

Emulating the Bose-Hubbard Model with Arrays of Superconducting Qubits William D. Oliver, Massachusetts Institute of TechnologyEvent Type: Physics Dept Colloquium Date: Thursday, December 10, 2026 Time: 4:00 PM - 5:30 PM Location: 726 Broadway, 940, CCPP Seminar Abstract: In this talk, we study the propagation, entanglement, and entropy of quantum information using 3x3 and 4x4 arrays of superconducting qubits that emulate the two-dimensional (2D) hard-core Bose-Hubbard model. The 2D arrays feature site-selective, simultaneous control and readout of all qubits. We highlight several recent experimental demonstrations using these arrays, including quantum random walks, Anderson and Wannier-Stark localization [1], the crossover from area-law to volume-law entanglement [2], the realization of synthetic electromagnetic fields throughout the array [3], and studies of flat-band physics in rhombic lattices [4].

Udi Nakar, Tel Aviv University| Event Type: Astro Seminar | Date: Tuesday, October 20, 2026 | Time: 2:00 PM - 3:15 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: A stellar explosion launches a radiation-mediated shock that propagates through the star and breaks out when the optical depth ahead of it becomes too low to sustain the shock. The photons released during shock breakout are the first electromagnetic signal from a cosmic explosion and carry unique information about the medium the shock emerges from, including its geometry, radius, composition, and density profile.
In this talk, I will discuss the distinctive properties of radiation-mediated shocks and describe the resulting breakout emission in a variety of cosmic explosions. I will highlight some of the things that observations of shock breakout and early emission have taught us so far, and some of what we expect to learn over the coming decade. | | ||||||

| A Path to the Analytic Thermal Bootstrap | |||||||||||
Alessio Miscioscia, Stony Brook| Event Type: HEP Seminar | Date: Wednesday, October 21, 2026 | Time: 2:00 PM - 3:00 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: I will discuss how thermal data, especially thermal two-point functions, can be constrained by a combination of the KMS condition, analyticity, clustering, and the OPE. In particular, I will propose KMS-symmetric dispersion relations for two-point functions. Crucially, only operators contributing to the discontinuity appear in these formulas, and the blocks are explicitly KMS-symmetric, in analogy with Polyakov blocks at zero temperature. The price to pay is an unknown arc function, which can be completely determined using the remaining properties of correlation functions.
Owing to the manifest periodicity of the expansion, I will also discuss the momentum-space version of this construction, making its connection with quasinormal modes (QNMs) explicit. These equations provide a complete bootstrap problem for the QNMs. I will illustrate the framework with free, perturbative, and large-(N) examples, including holographic correlators, and mention applications to the 3D Ising model. | | ||||||

| Towards Positivity Bounds for the Effective Field Theory of Inflation | |||||||||||

Whether reliable and widely applicable positivity bounds can be derived for such theories remains an open question.
I will first review the obstacles faced by standard methods and discuss an alternative approach. I will then introduce an object with good analyticity properties whose high-energy behaviour can be controlled.
Finally, I will explain why, despite this, the construction does not generally yield positivity bounds and discuss a possible way forward. | | ||||||

| Electromagnetic signatures of massive black hole binary mergers and their identification in multi-messenger observations | |||||||||||
Chengcheng Xin, Harvard University | Black Hole Initiative| Event Type: Astro Seminar | Date: Tuesday, November 3, 2026 | Time: 2:00 PM - 3:00 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: Massive black hole binaries (MBHBs) are a natural outcome of galaxy mergers and are expected to be among the strongest sources of low-frequency gravitational waves. At sub-parsec separations, however, these binaries are extremely difficult to resolve directly. One promising approach is to search for their signatures in the time-domain variability of AGN lightcurves. Orbital motion can imprint periodic or evolving (“chirping”) signals in quasar light curves through mechanisms such as relativistic Doppler boosting. In this talk, I present a series of studies exploring methods for detecting compact SMBHBs in large optical surveys, building towards a systematic search. Using mock data motivated by the new time-domain survey LSST, we evaluate the performance of these methods. I will demonstrate that both periodic and chirping signals, consistent with GW-driven inspiral, can be identified in large optical surveys alone, and that these detections can be confirmed with even higher confidence when combined with GW observations. Finally, I will discuss a potential multi-wavelengths signature of MBHBs due to multiple disk- and jet- components. | | ||||||

| Inference through Compression: Learning the Physics of Multicomponent Systems | |||||||||||
William Jacobs, Princeton University| Event Type: Physics Dept Colloquium | Date: Thursday, November 12, 2026 | Time: 4:00 PM - 5:30 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: Physical understanding benefits from simplicity and interpretability, yet quantitative prediction in complex systems often demands much richer descriptions. In this talk, I will show how compression can be used to extract physical insights from systems in which the microscopic details still matter quantitatively. Using examples drawn from heteropolymers, biomolecular systems, and programmable soft matter, I will demonstrate that the thermodynamic structure of multicomponent systems can itself be compressed, so that molecules acquire low-dimensional representations through their interactions with other components. These representations retain the relevant physical information while enabling quantitatively accurate predictions of thermodynamic properties across a wide range of mixtures and conditions. By revealing which microscopic details control collective behavior, this approach provides a systematic route to infer effective variables, extrapolate to new systems and conditions, and rationally design multicomponent matter. | | ||||||
| How Dust Evolution Shapes Protoplanetary Disks | |||||||||||
Thomas Pfeil, CCA| Event Type: Astro Seminar | Date: Tuesday, November 17, 2026 | Time: 2:00 PM - 3:15 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: " Planet formation begins with the coagulation of micrometer-sized dust grains in a protoplanetary disk. This particle growth not only provides the building material for planetesimals but also shapes the environments they form in.
Aerodynamic drag forces between gas and dust determine how fast the grains drift and how efficiently they can be trapped in the frequently observed rings and vortices in protoplanetary disks. The size of the particles thus affects the available dust mass and composition throughout the disk. Dust also dominates the opacities and therefore regulates the thermal structure and the onset of hydrodynamic instabilities that depend on thermal relaxation.
In my talk, I will present two recent applications of coupled multifluid simulations and dust coagulation models that capture the interplay of microphysics and large-scale dynamics in protoplanetary disks:
Our simulations of planet-disk systems with dust coagulation quantify the amount of small dust grains that diffuse and drift through planet-induced gaps. These calculations constrain the composition and available mass of solids in the inner disk regions.
We furthermore investigate the effects of dust evolution on protoplanetary disk turbulence, induced by the Vertical Shear Instability. Our simulations show that efficient dust coagulation can suppress turbulence in protoplanetary disks, due to the reduced collisional cooling in the dust-depleted upper layers.
Understanding how dust coagulation influences the dynamics of protoplanetary disks is thus key to understanding the initial conditions for planet formation and to interpreting multi-wavelength observations." | | ||||||

| The Slow Creep of Glacial Ice: A Multiscale Disordered Material | |||||||||||
Justin Burton, Emory University| Event Type: Physics Dept Colloquium | Date: Thursday, November 19, 2026 | Time: 4:00 PM - 5:30 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: One of the largest uncertainties for future predictions of sea level rise is the dynamic mass loss of ice into the ocean. Icebergs break off from ocean-terminating glaciers and form granular piles that jam up future calving events. In this iceberg purgatory, a floating granular mélange, forces are transmitted through contacts between individual icebergs 10-100 meters in size. Further upstream, before reaching the ocean, bulk glacial ice creeps slowly over time, behaving like a non-Newtonian liquid where the relationship between stress and deformation rate is a key factor for making predictions about the stability of ice shelves and ice sheets. Glacial ice is composed of polycrystalline grains that can be centimeters in size and form a disordered network of grain boundaries separating crystal orientation. Within each grain are disordered arrays of dislocations whose dynamics determine molecular-scale creep. Within this multiscale problem, I will primarily focus on the slow creep of glaciers, from molecules to grains. Recently we developed a physics-based rheological model that captures all three regimes of transient creep in polycrystalline ice under constant stress. The model replicates the minimum strain rate near 1% strain, which results from a competition of two timescales that depend on the driving stress. The model also exhibits apparent power-law exponents in the stress dependence of the strain-rate minimum, which is a quantity often reported in experimental data and directly used in large-scale climate models. | | ||||||

I will first discuss how the AI chatbox can help understand and push forward a project under human's control. Then, I will discuss how AI agents work, from giving them specific calculation tasks to asking them to explore a vague research idea. I will discuss some difficulties I encountered during this AI-assisted workflow. In particular, sometimes the agent moved away from the physical setting of the project, or continued developing an argument before I understood the previous steps. Based on these experiences, I will discuss how to better work with AI, check its results, and keep track of the direction of a research project. The focus will be on practical research experience rather than the technical details of AI, so no prior knowledge of AI is needed. | | ||||||
| Gravitational-wave and electromagnetic signatures of binary black holes with circumbinary gas | |||||||||||
Zoltan Haiman, IST Austria| Event Type: Astro Seminar | Date: Tuesday, November 24, 2026 | Time: 2:00 PM - 3:15 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: Binary black holes (BHBs) embedded in dense gas hold the promise of "multi-messenger astrophysics": when they are detected both through gravitational waves (GWs) and electromagnetic (EM) observations, they will enable novel science. This is true both for massive BHBs, whose GWs will be detectable by the future LISA satellite and by on-going pulsar timing arrays (PTAs), as well as for stellar-mass BHBs detected through ground-based GW detectors. In both cases, identifying coalescing binaries through their EM signatures will help clarify their astrophysical origin and yield novel probes of cosmology, fundamental physics, and accretion physics. In this talk, I will describe how circumbinary gas may impact the orbital evolution of binaries, while producing characteristic EM signatures for both massive and stellar-mass BHBs, based on hydrodynamical simulations and analytic models. In both cases, several binary candidates have been identified in optical surveys, and LSST should soon be able to uncover robust binaries based on their high-quality, multi-band light-curves. | | ||||||

| Using Tidal Disruption Events as Probes of Massive Black Hole Formation and Growth Over Cosmic Time | |||||||||||
Suvi Gezari, University of Maryland| Event Type: Astro Seminar | Date: Tuesday, December 1, 2026 | Time: 2:00 PM - 3:15 PM | Location: 726 Broadway, 940, CCPP Seminar | Abstract: The tidal disruption of a star that wanders too close to a central black hole is a unique probe of quiescent supermassive black holes lurking in the nuclei of galaxies. We have demonstrated the ability to discover and spectroscopically classify large samples of tidal disruption events (TDEs) in the optical from the Zwicky Transient Facility (ZTF) Northern Sky Survey, with systematic high-energy follow-up with Swift and XMM-Newton. From these efforts, we now know the spectroscopic signatures, multi-wavelength properties, and host galaxy preferences of TDEs, and can begin to use TDEs as powerful probes of massive black hole demographics in quiescent galaxies. One of the most exciting applications of TDEs is the ability to probe intermediate mass black holes (IMBHs) that are expected to reside in dwarf galaxies, with demographics that encode the seeding mechanism of massive black holes in the early Universe. I will outline our strategy in the next decade for searching for TDEs across the black hole mass function, and over cosmic time, by extending our sensitivity to TDEs to lower central black hole masses and higher redshifts, by exploiting the discovery power of the next generation of wide-field time domain surveys, including Rubin, Roman, ULTRASAT, and UVEX. | | ||||||

The 2D arrays feature site-selective, simultaneous control and readout of all qubits. We highlight several recent experimental demonstrations using these arrays, including quantum random walks, Anderson and Wannier-Stark localization [1], the crossover from area-law to volume-law entanglement [2], the realization of synthetic electromagnetic fields throughout the array [3], and studies of flat-band physics in rhombic lattices [4].
