The rise of multi-Petawatt lasers opens new frontiers in exploring the quantum vacuum. This study presents real-time 3D simulations of vacuum birefringence and four-wave mixing, based on a semi-classical numerical solver integrated into a Particle-In-Cell code OSIRIS, capable of tracking the evolution of non-linearities.
