Abstract
The detailed numerical investigation of the highly nonlinear physics involved in the interaction of a laser-pulse with a plasma and/or an externally injected beam requires suitable simulation tools which are able to retain the basic features of the process without increasing too much the computational needs. In our group at the University of Bologna we developed an electromagnetic PIC code using high-order schemes (explicit/compact finite differences derivatives and a 4th-order Runge-Kutta) instead of the most used second-order accurate algorithm, this allows to reach higher accuracy with similar number of grid-points or to use coarser grid and relax the computer load without compromising the accuracy. Here we present some validation tests and comparisons for the different schemes.
