Vacuum birefringence at x-ray free-electron lasers

We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone.We devise an experimental scheme allowing two consecutive stickers logos dallas cowboys XFEL pulses to collide under a finite angle, and thus act as both pump and probe field for the effe
