Macroscopic Coherent Axion Production by Reverse Parametric Fluorescence
Zhan Bai, Baifei Shen, Liangliang Ji +1
We propose a macroscopically coherent laboratory source of axion-like particles (ALPs) through the axion--electron coupling \(g_{ae}\). Two counterpropagating optical modes drive r…

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…
