Structure of strongly coupled multicomponent plasmas.

We investigate the short-range structure in strongly coupled fluidlike plasmas using the hypernetted chain approach generalized to multicomponent systems. Good agreement with numerical simulations validates this method for the parameters considered. We found a strong mutual impact on the spatial arrangement for systems with multiple ion species which is most clearly pronounced in the static structure factor.

Collisional absorption of dense plasmas in strong laser fields: quantum statistical results and simulation.

Collisional absorption of dense fully ionized plasmas in strong laser fields is investigated using quantum statistical methods as well as molecular dynamics simulations. For high-frequency fields, quantum statistical expressions for the electrical current density and the electron-ion collision frequency are presented. Strong correlations are taken into account and their influence on the absorption rate is discussed.

Nonlinear collisional absorption in dense laser plasmas.

Collisional absorption of dense, fully ionized plasmas in strong laser fields is investigated starting from a quantum kinetic equation with non-Markovian and field-dependent collision integrals in dynamically screened Born approximation. This allows to find rather general balance equations for the energy and the current. For high-frequency laser fields, quantum statistical expressions for the electrical current density and the cycle-averaged electron-ion collision frequency in terms of the Lindhard dielectric function are derived.
