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…
Cosmology with varying fundamental constants from hyperlight, coupled scalars
Masha Baryakhtar, Olivier Simon, Zachary J. Weiner
The fundamental constants at recombination can differ from their present-day values due to degeneracies in cosmological parameters, raising the possibility of yet-undiscovered phys…
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…
