Searching for coupled, hyperlight scalars across cosmic history

Masha Baryakhtar, Olivier Simon, Zachary J. Weiner

Cosmological scalar fields coupled to the Standard Model drive temporal variations in the fundamental constants that grow with redshift, positioning the early Universe as a powerfu…

Scalar relics from the hot Big Bang

David Cyncynates, Olivier Simon

In this Letter, we motivate the fact that couplings between a scalar field and the Standard Model with strengths relative to gravity yield the total…

Minimal targets for dilaton direct detection

David Cyncynates, Olivier Simon

Fifth force and equivalence principle tests search for new interactions by precisely measuring forces between macroscopic collections of atoms and molecules and their properties un…

Nonperturbative structure in coupled axion sectors and implications for direct detection

David Cyncynates, Olivier Simon, Jedidiah O. Thompson +1

Pairs of misalignment-produced axions with nearby masses can experience a nonlinear resonance that leads to enhanced direct and astrophysical signatures of axion dark matter. In mu…

Dark Matter In Extreme Astrophysical Environments

Masha Baryakhtar, Regina Caputo, Djuna Croon +37

Exploring dark matter via observations of extreme astrophysical environments -- defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well…

Dark QED from Inflation

Asimina Arvanitaki, Savas Dimopoulos, Marios Galanis +3

One contribution to any dark sector's abundance comes from its gravitational production during inflation. If the dark sector is weakly coupled to the inflaton and the Standard Mode…
