Optical properties of cosmic void

by Dr Adam Smetana (Institute of Experimental and Applied Physics, CTU in Prague)

Thursday 6 Jun 2024, 14:00 → 15:00 Europe/Prague

Abstract: 

Interferometric responses of the electromagnetic waves are one of the most sensitive probes of the properties of the propagation media. The cutting edge interferometers (LIGO, VIRGO) with unprecedented precision has recently opened the gravitational wave window to the universe. That is one example of the power of interferometric technologies to detect the most elusive physical phenomena. In this presentation we review few approaches towards an interferometric detection of some of the most subtle astroparticle and cosmological substances, like relic neutrinos and dark matter. That consists of embracing two main optical phenomena which are the birefringence related to the optical activity, and variation of the index of refraction. We also mention the limitations of the space-based interferometric gravitational waves antennas (like LISA) given by modulation of the index of refraction of the interplanetary void by solar wind density variations.
