Physics beyond the Standard Model with the DSA-2000
Kim V. Berghaus, Yufeng Du, Vincent S. H. Lee +4
The upcoming Deep Synoptic Array 2000 (DSA-2000) will map the radio sky at GHz (eV) with unprecedented sensitivity. This will enable searches for dark matt…

Detecting gravitational signatures of dark matter with atom gradiometers
Leonardo Badurina, Yufeng Du, Vincent S. H. Lee +2
We study the purely gravitational signatures of dark matter from the ultralight to the ultraheavy mass range in proposed long-baseline atom gradiometers, focusing on terrestrial de…

Signatures of linearized gravity in atom interferometers: A simplified computational framework
Leonardo Badurina, Yufeng Du, Vincent S. H. Lee +2
We develop a general framework for calculating the leading-order, general relativistic contributions to the gravitational phase shift in single-photon atom interferometers within t…
