Abstract

Based on quantum statistical theory a kinetic equation is presented which is valid for dense plasmas in time-dependent electromagnetic fields. It generalizes previous results to quantum systems. Starting from this equation the collision frequency and the electrical conductivity for quantum plasmas in strong high-frequency laser fields are calculated without using any external cutoff-procedure. The influence of nonlinear field as well as plasma density effects on the collision frequency and on the conductivity is discussed. Finally, the results are compared with that obtained from the well-known classical theories.
