Region of validity of the Thomas–Fermi model with corrections

A new method to calculate thermodynamically consistent shell corrections in a wide range of parameters is used to predict the region of validity of the Thomas-Fermi approach. The method is applicable both at low and high density. Thermodynamic functions of electrons calculated by the Thomas–Fermi model are compared with quantum, exchange, and shell corrections. The corrections become quite big at moderate and low densities and low temperatures in the region of strongly coupled plasma.

First-principle simulation of shock-wave experiments for aluminum

We present first-principle calculations of shock Hugoniots, release isentropes and sound speed measurements on the principle Hugoniot of aluminum. Most of the results are in good agreement with experiments and a wide-range equation of state.

Region of validity of the Thomas–Fermi model with quantum, exchange and shell corrections

A novel approach to calculate thermodynamically consistent shell corrections in wide range of parameters is used to predict the region of validity of the Thomas-Fermi approach. Calculated thermodynamic functions of electrons at high density are consistent with the more precise density functional theory. It makes it possible to work out a semi-classical model applicable both at low and high density.
