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…
Cosmology with the angular cross-correlation of gravitational-wave and galaxy catalogs: Forecasts for next-generation interferometers and the Euclid survey
Alessandro Pedrotti, Michele Mancarella, Julien Bel +2
The spatial clustering of galaxies has long been a key probe of cosmology. Gravitational-wave (GW) sources, which provide direct luminosity-distance measurements, have recently eme…
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…
