Precision measurements unraveling gravitational waves and dark matter

by Nancy Aggarwal (UC Davis)

Tuesday 18 Jun 2024, 16:00 → 18:00 Europe/Berlin

Auditorium (DESY Hamburg)

Gravitational waves (GWs) at frequencies higher than the LIGO band can bring us completely new information about the universe. In this talk I will talk about a new network of tabletop detectors to look for radio frequency gravitational waves (GWs) using optically levitated sensors. I will also summarize projects looking for dark matter signals in GW-detectors in multiple frequency bands.
In the second part of the talk, I will describe an experiment searching for the QCD axion in the μeV-meV mass range mediating new spin-dependent forces in the laboratory - a precision measurement experiment that requires isolating a force equivalent to a magnetic field of 10⁻²⁰ T between golf-ball sized, moving objects, placed 50 microns away from each other.

We invite you to join the presentation in the DESY auditorium. We also offer a webcast:
