Natural Phantom Crossing from Axion-WIMP Interactions
Cédric Delaunay, Seung J. Lee, Yuan Yin +1
We construct a technically natural model in which thermal dark matter (DM) interacts with axion dark energy (DE) and produces an apparent late-time crossing of the phantom divide.…

Probing New Forces with Nuclear Clocks
Cédric Delaunay, Seung J. Lee, Roee Ozeri +3
Clocks based on nuclear isomer transitions promise exceptional stability and precision. The low transition energy of the thorium-229 isomer makes it an ideal candidate, as it has b…

Axion dark matter from inflation-driven quantum phase transition
Ameen Ismail, Seung J. Lee, Bingrong Yu
We propose a new mechanism to produce axion dark matter from inflationary fluctuations. Quantum fluctuations during inflation are strengthened by a coupling of the axion kinetic te…
