| Some Aspects of Krylov Complexity | |
| Eliezer Rabinovici, Hebrew University of Jerusalem | |
| Event Type: Informal HEP Talk | |
| Time: 11:00 AM - 12:00 PM | |
| Location: 726 Broadway, 940, CCPP Seminar | |
| Abstract: A review of the concept of Krylov Complexity(K- Complexity) will be presented. One feature of K-Complexity is that its definition does not involve a tolerance parameter. I will describe some general properties of K-Complexity, its behavior when interpolating among various types of systems: free, strongly integrable and chaotic ones. Finally for a certain low dimensional system in a certain state I will describe an explicit derivation of the geometric bulk dual of K complexity. | |
| Behind and Beyond the Standard Model | |
| Riccardo Rattazzi, École Polytechnique Fédérale de Lausanne | |
| Event Type: Physics Dept Colloquium | |
| Time: 4:00 PM - 5:30 PM | |
| Location: 726 Broadway, 940, CCPP Seminar | |
| Abstract: Relativity and Quantum Mechanics are the basis of our present understanding of fundamental physics as embodied by the Standard Model (SM) of particle physics. However, like all else in physics, the SM is itself expected to be the macroscopic manifestation of yet unknown microscopic physics. While remaining at the surface of things, I will analyze in that vein the structure of the SM and of some of its possible extensions. I will thus illustrate the often debated and mis-debated Hierarchy Paradox and assess the role of present and future experimental studies. | |
