Effective potentials, energies, and pair-distribution functions of plasmasby Monte-Carlo simulations

The one-component plasma (OCP), an electron gas on a positive background, a nd the subsystem of free charges in a two-component plasma (TCP) is investi gated using a quasi-classical approach. Quantum effects such as the Heisenb erg uncertainty principle and the Pauli exclusion principle are incorporate d into our model by effective potentials. In case of the OCP the symmetry e ffects are of special interest whereas in case of TCP the Heisenberg effect s play the significant role. The method of Slater sums is used to obtain ef fective potentials. Monte Carlo simulations for both OCP and TCP were carri ed out to calculate the Coulombic energy, the effective energy, and the pai r-distribution functions.
