Stopping power in strongly correlated plasmas

The energy loss of charged particles in a plasma is of high current interest. Despite the efforts of many researchers over the last decades, many problems remain still unsolved. This is in particular true for strongly coupled plasmas. Generated by laser or shock compression, these plasmas reach solid state densities. Related problems occur in inertial confinement fusion situations. The interaction energy of such plasma is of the order of the kinetic energy. Therefore, a charged particle, penetrating a nonideal plasma will interact with the plasma in a different way. Its energy loss will be strongly influenced by many-particle effects, such as dynamical screening, collective excitations, instabilities and degeneracy. These effects can be accounted for in quantum kinetic equations, such as the Lenard-Balescu equation. It has been successfully applied to calculations of the stopping power of charged particle beams. However, so fax the calculations have been restricted to initial or stationary state situations. Therefore, we carry out a dynamical investigation, considering the thermalization process of a particle beam in a background plasma solving the Balescu equation with the correct selfconsistent Lindhard dielectric function
