Super light-by-light scattering in vacuum induced by intense vortex lasers
Zhigang Bu, Lingang Zhang, Shiyu Liu +4
Collision of ultra-intense optical laser and X-ray free electron laser (XFEL) pulses is a promising approach to detecting nonlinear vacuum polarization (VP), a long-standing predic…

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…
