Description
Summary:The nonlinear evolution of plasma waves in quantum plasmas is studied up to and beyond the wavebreaking limit. Wavebreaking sets basic limitations to hydrodynamic models. In this work, a complete quantum kinetic computational approach is presented. Linear dispersion relations and Landau damping rates can be accurately reproduced by this method. In the nonlinear regime wavebreaking amplitudes in quantum plasmas are obtained and compared to theoretical results. Specific quantum effects can be explained by a nonlinear coupling of plasmon to free-particle modes in the wavebreaking regime.
