In … Web4 de jul. de 2015 · One very fundamental physical question that can be addressed in this constellation is the direct observation of vacuum birefringence-a fundamental consequence of quantum electrodynamics (QED).

Experimental observation of vacuum birefringence Request PDF

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 … WebWe consider the possibility of an experimental proof of vacuum pair creation in the focus of two counter-propagating optical laser beams with an intensity of the order of 10-10 W/cm. Our approach is based on the colli… how mitosis affects plant growth
