High Precision Fundamental Physics Experiments at JLab with Spin-transparent Storage Rings of Low-energy Polarized Electron Beams

Vladimir Khachatryan, Riad Suleiman, Alberto Accardi +27

A breakthrough in fundamental physics experiments measuring particle spin precession may happen if spin-transparent storage rings become adopted tools for such experiments. We pres…

Apparent Lorentz violation from disformally coupled ultralight dark matter

Guillem Domènech, Apostolos Tsabodimos, Apostolos Tsampodimos +3

We study the impact of general disformal metric transformations on fermions, which shift the gravitational metric by an additional rank-2 tensor. This tensor can in principle be co…

Probing Grand Unification with Quantum Sensors

Xavier Calmet, Nathaniel Sherrill

We discuss how grand unification can be probed with experiments at low energies using quantum sensors. Specifically, we show that scalar multiplets coupled to the gauge sector of a…

Analysis of atomic-clock data to constrain variations of fundamental constants

Nathaniel Sherrill, Adam O. Parsons, Charles F. A. Baynham +13

We present a new framework to study the time variation of fundamental constants in a model-independent way. Model independence implies more free parameters than assumed in previous…

Implications of Quantum Gravity for Dark Matter Searches with Atom Interferometers

Xavier Calmet, Nathaniel Sherrill

In this brief paper, we show that atom interferometer experiments such as MAGIS, AION or AEDGE have the potential to not only probe very light dark matter models, but they will als…

Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map

Ivan Alonso, Cristiano Alpigiani, Brett Altschul +246

We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportu…

Measuring the stability of fundamental constants with a network of clocks

G. Barontini, L. Blackburn, V. Boyer +41

The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…

QSNET, a network of clocks for measuring the stability of fundamental constants

G. Barontini, V. Boyer, X. Calmet +19

The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure…
