Multimessenger Astronomy Beyond the Standard Model: New Window from Quantum Sensors
Jason Arakawa, Muhammad H. Zaheer, Volodymyr Takhistov +3
Ultralight bosonic (ULB) fields with mass ~eV often arise in theories beyond the Standard Model (SM). If such fields exist, violent astrophysical events that result in…

Probing Ultralight Dark Matter at the Mega-Planck Scale with the Thorium Nuclear Clock
Jason Arakawa, Jack F. Doyle, Elina Fuchs +10
Ultralight dark matter is expected to induce oscillations of nuclear parameters. These oscillations are characterized by extremely weak couplings or high suppression scales, with t…

Phase Separation Unlocks Resonant Leptogenesis
Jason Arakawa, Philip Lu, Volodymyr Takhistov
Distinct behavior of decaying particles in true and false vacua of the theory can lead to enhanced generation of baryon asymmetry, a scenario we call \textit{phase separation baryo…
