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 …

Web22 de jun. de 2024 · Vacuum birefringence (VB) is a basic phenomenon predicted in quantum electrodynamics (QED). However, due to the smallness of the signal, conventional magnet-based and extremely intense laser-driven detection methods are still very challenging. This is because in the first case the interaction length is large but the field is … Web1 de mar. de 2007 · @article{osti_21020043, title = {Rotation of a magnetic field does not impact vacuum birefringence}, author = {Biswas, Sandip and Melnikov, Kirill}, abstractNote = {We study how the rotation of a classical magnetic field influences vacuum birefringence.
