Particle-In-Cell simulations for highly oscillatory Vlasov-Poisson systems

We propose a time-stepping algorithm for solving 2d and 4d multi-scale Vlasov-Poisson systems
in a Particle-In-Cell framework. The new scheme allows to use large time steps
compared to the size of the oscillations in the solution. We discuss the accurate long time behaviour and
the asymptotic-preserving property with respect to the limiting system.
