-dispersionless solver for electromagnetic and axion fields in a cylindrical particle-in-cell code

Xiangyan An, Min Chen, Yipeng Wu +3

We develop a quasi-cylindrical direction-splitting (QDS) dispersionless Maxwell solver for the open-source EPOCH particle-in-cell framework. The method preserves the exact axial ph…

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…

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…

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…

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…
