First principle thermodynamic and dynamic simulations for dense quantum plasmas

摘要

We present a detailed analysis of temperature-dependent effective quantum pair potentials. These potentials are derived from first-principle path integral Monte Carlo simulations and are accurate even at strong coupling and partial ionization. They can be efficiently used in molecular-dynamics (MD) simulations to obtain accurate thermodynamic and dynamic properties of strongly coupled hydrogen down to the temperatures of about 60 000 K. Furthermore, using spin-dependent pair potentials, dynamic structure factors and spin-density correlation functions were calculated for different values of coupling and degeneracy.
