Sudden Decoherence by Resonant Particle Excitation for Testing Gravity-Induced Entanglement
Youka Kaku, Akira Matsumura, Tomohiro Fujita
We propose a novel method to probe gravity-induced entanglement. We consider the gravitational interaction between a particle trapped in a shallow potential and a harmonic oscillat…

Adjusting optical cavity birefringence with wavelength tunable laser for axion searches
Hinata Takidera, Hiroki Fujimoto, Yuka Oshima +6
Axions have attracted attention as promising candidates for dark matter (DM). Although axions have been intensively searched for, they have not been observed yet. Recently, novel e…

Reheating after Axion Inflation
Tomohiro Fujita, Kyohei Mukaida, Tenta Tsuji
We investigate the reheating process in an axion inflation model where the inflaton couples to non-Abelian gauge fields via the Chern-Simons coupling. The Chern-Simons coupling lea…
