Vacuum-Triggered Instability in Paired Superradiance
Zhan Bai, Ningqiang Song, Min Chen +4
Paired superradiance (PSR) is a macro-coherent two-photon process capable of very large gain, making it promising for detecting ultra-weak signals induced by neutrinos or dark matt…
Acceleration of Ultrahigh Energy Particles from Fast Radio Bursts
Lin Yu, Tianxing Hu, Zhiyu Lei +6
Two extreme events in the universe, fast radio bursts (FRBs) and cosmic rays (CRs), could be correlated, where FRBs with extreme field strength near their sources may contribute to…
Axion generation and detection in laser-plasma wakefields
Xiangyan An, Min Chen, Jianglai Liu +4
The axions are compelling candidates for cold dark matter, but their extremely weak interaction with photons makes laboratory searches challenging. We show that the quasi-static el…
Coherently Enhanced Axion-Photon Conversion via Seeded Photons for Short-Pulse Axion Detection
Xiangyan An, Min Chen, Jianglai Liu +7
We propose a seeded axion-photon conversion scheme to enhance the sensitivity of light-shining-through-a-wall (LSW) experiments for axion detection, where the axions are generated…
Coherent Axion Production through Laser Crystal Interaction
Zhan Bai, Xiangyan An, Yuqi Chen +3
We investigate the interaction between an optical laser and an ionic crystal and reveal coherent emission of axions through phase-match between laser and axion fields. Such emissio…
