摘要
This work is an improved continuation of a previous attempt to use classical molecular dynamics (MD) as a tool for the investigation of hot and dense "real" plasmas. "Real" in this context refers to ions and electrons interacting through Coulomb forces and undergoing ionization/recombination. The objective of designing such a non standard approach to plasma equilibrium is to explore a new way to discuss warm and dense matter with a method able to deal with the whole complexity of a N-body system of ions and electrons. Plasma relaxation times can be investigated up to a picosecond. The resulting equilibrium ion populations, built self consistently, are comparable to those found in literature and, potentially validate access to all the statistical data usually derived from MD simulations.
