Applications of the Heisenberg-Euler Weak-Field Expansion Simulator

With the advent of high power lasers, the experimental detection of dynamic quantum vacuum effects comes within reach giving reason to the need of advanced numerical simulations. To understand quantum electrodynamics (QED) the numerical approach is inevitable. While most of the numerical solvers have problems in the effective QED regime, our solver is capable of simulating different scenarios in the Heisenberg-Euler regime in the weak-field limit in multiple dimensions and for a variety of scenarios reliably. In the talk multiple setups are introduced and discussed by simulating colliding laser pulses. In particular, the phenomenon of light-by-light focusing is addressed and simulated in two dimensions and in addition setups of flipping scenarios are covered.
