Close Pulsar Pairs See Dark Matter Substructure through the Gravitational-Wave Background
Abhiram Cherukupalli, Vincent S. H. Lee, Kim V. Berghaus +1
Pulsar timing arrays detect signals from dark matter substructure, but a nanohertz gravitational-wave background (GWB) severely degrades their sensitivity. We show that timing puls…
Pulsar Timing Sensitivity to Dark Matter Substructure in the Presence of a Stochastic Gravitational-Wave Background
Abhiram Cherukupalli, Vincent S. H. Lee, Kim Berghaus +1
Pulsar timing arrays (PTAs) can detect dark matter (DM) substructure through the small shifts a transiting DM subhalo imprints on pulse arrival times. Recently found evidence for a…
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 matte…
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…
Quantum Area Fluctuations from Gravitational Phase Space
Luca Ciambelli, Temple He, Kathryn M. Zurek
We study the gravitational phase space associated to a stretched horizon within a finite-sized causal diamond in -dimensional spacetimes. By imposing the Raychaudhuri equati…
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…
