I will argue that reflection of relic neutrinos from the surface of the Earth creates a significant local neutrino-antineutrino asymmetry in a shell seven meters thick around the Earth's surface. This asymmetry far exceeds the expected primordial lepton asymmetry. The resulting gradient of the net neutrino density provides a way-out of a forty-year-old “no-go” theorem on the vanishing of O(G_Fermi) neutrino forces on matter. These forces can be further enhanced by using 1-100 meter structures with shape reminiscent of a sea-urchin: they consist of rods of width w and length L>>w periodically arranged on the surface of the sphere of radius R~L. Such a structure functions as a diffraction grating for relic neutrinos and the induced neutrino-antineutrino asymmetry at its center may point to a new class of experiments to detect the CνB in a laboratory setting. At the same time, such structures can be used to similarly manipulate dark matter. | 30 Chiara Mingarelli, The NANOGrav Experiment: Current Results and Future Directions (3:00 PM - 4:30 PM) + Abstract: | 1 Popov, Postdoc HepTh Discussion Group (12:00 PM - 1:30 PM) James Sullivan, Galaxies Remember Inflation - New Aspects of Local Primordial non-Gaussianity in Galaxy Surveys (12:00 PM - 12:30 PM) + Abstract: |
