On the observation of vacuum birefringence

WebWe suggest an experiment to observe vacuum birefringence induced by intense laser fields. A high-intensity laser pulse is focused to ultra-relativistic intensity and polarizes the vacuum which then acts like a birefringent medium. The latter is probed by a linearly polarized X-ray pulse. We calculate the resulting ellipticity signal within strong-field QED … Web4 de jul. de 2024 · Earlier we used this Lagrangian (Karplus and Neuman 1950) to solve the problem of birefringence of vacuum in presence of a counterpropagating electromagnetic wave (Prakash and Shukla 2007). In earlier work we studied the birefringence of vacuum in presence of a counter propagating electromagnetic wave and found that quite large …
