Vlasov simulations are attractive due to the low numerical noise, in particular in studies of mildly nonlinear wave-wave and wave-particle interactions, or when the low-density tail of the momentum (or velocity) distribution function has to be resolved accurately. Examples include the Raman instability, investigations of nonlinear kinetic structures (Bernstein-Greene-Kruskal-like modes), and the coupling to electron Bernstein modes in magnetized plasma [1,2]. Lower-dimensional Vlasov simulations can show good convergence and thus become an attractive complement to particle-in-cell simulations. The conservation of transverse canonical momentum is conveniently used to reduce the number of momentum dimensions in Vlasov simulations of relativistic laser-plasma interactions , and in more general cases fluid moments can be taken in transverse directions and fully kinetic modelling kept along dominant directions. We will present Vlasov simulations of relativistic laser-plasma interactions [2,4], the interaction with electron and ion holes in plasmas , and parametric interactions with electron Bernstein waves in magnetized plasmas .Reference B.
