The purpose of this paper is to illustrate our contribution to general plasma physics studies obtained since the 90s with multiple versions and adaptations of the classical molecular dynamics (CMD) simulation interactive code called BinGo. After a description of the particulars of the CMD simulation models and the BinGo code suite, some applications are discussed for illustration. These results validate the CMD simulation as a powerful tool of investigation for hot dense plasmas. [ABSTRACT FROM AUTHOR]

A classical Molecular Dynamics code has been developed to simulate dense plasmas i.e. neutral systems of interacting ions and electrons. Our goal is to design a tool that relies on a reduced set of microscopic mechanisms in order to obtain solutions of complex time dependent N-body problems and to allow an efficient description of the plasma states between classical high temperature systems to strongly coupled plasmas. Our present objective is an attempt to explore the behavior of such a classical approach for typical conditions of warm dense matter. We calculate the dynamic structure factor in warm dense beryllium by means of our molecular dynamics simulations. The results are then compared with those obtained within the framework of the random phase approximation (RPA). [ABSTRACT FROM AUTHOR]

Abstract: We have investigated the solvation shell dynamics of Na+ and Cl− ion pairs in water - DMSO mixtures of three compositions with (mole fraction of DMSO) 0.21, 0.35 and 0.48. Dynamical ion pair trajectories in these compositions are studied to analyze the diffusional behaviour of the solvent molecules in the primary and secondary solvation shells as well as the bulk solvent. As expected, the diffusivity of the primary solvation shells is smaller than the bulk. The insertion of solvent molecules in the region between the ion pairs during the ion pair separation process is analyzed from the classical ion pair molecular dynamics trajectories in these compositions of water DMSO mixtures.

Abstract: 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.

Abstract: An ionization–recombination model based on three-body electron-ion collisions is implemented in classical molecular dynamics. A new ion–electron regularized potential is used to account for the ionization energies of the various ion stages. The purpose of the present work is to probe the feasibility of such an approach for providing qualitative information on charge dynamics for two component plasmas with special attention to strongly coupled conditions. An illustration of the technique is carried out for magnesium. [Copyright &y& Elsevier]
