Matter-Wave Interferometers as Open-System Dark Matter Detectors
Leonardo Badurina, Kathryn M. Zurek
Matter-wave interferometers (MWIs) offer a uniquely quantum route to dark matter (DM) detection: DM can reveal itself through phase and decoherence between spatially separated wave…
Ultralight dark matter detection with trapped-ion interferometry
Leonardo Badurina, Diego Blas, John Ellis +1
We explore how recent advances in the manipulation of single-ion wave packets open new avenues for detecting weak magnetic fields sourced by ultralight dark matter. A trapped ion i…
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…
Coherent collisional decoherence
Leonardo Badurina, Clara Murgui, Ryan Plestid
We study the decoherence of a system of non-interacting heavy particles (atoms) due to coherent scattering with a background gas. We introduce a framework for computing the ind…
