Precision measurements unraveling gravitational waves and dark matter
Nancy Aggarwal (UC Davis)
Auditorium (DESY Hamburg) and Zoom, 16:00h
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 person in the DESY Auditorium. We will also offer a webcast to this colloquium.
