  • The dynamics of hot and dense nuclear matter is discussed from the microscopic transport point of view. The basic concepts of the Hadron-String-Dynamical transport model (HSD)-derived from Kadanoff-Baym equations in phase phase-are presented as well as 'highlights' of HSD results for different observables in heavy-ion collisions from 100 A MeV (SIS) to 21 A TeV(RHIC) energies. Furthermore, a novel extension of the HSD model for the description of the partonic phase-the Parton-Hadron-String-Dynamics (PHSD) approach-is introduced. PHSD includes a nontrivial partonic equation of state-in line with lattice QCD-as well as covariant transition rates from partonic to hadronic degrees of freedom. Themore » sensitivity of hadronic observables to the partonic phase is demonstrated for relativistic heavy-ion collisions from the FAIR/NICA up to the RHIC energy regime.« less

  • Quantum molecular dynamics simulations of pure samples and of mixtures of isotopic hydrogenic species ({ital H}, {ital D}, {ital T}) yield important structural, dynamical, and electronic properties that characterize matter at high compressions ({rho}{ge}0.25 g/cm{sup 3}) and moderate temperatures (3000--60 000 K). Quantum mechanical treatments of the electrons, contained in periodically replicated reference cells of {ital N}{sub {ital a}} atoms, by density functional and tight-binding methods determine the force on the nuclei and the electronic structure of the medium. The nuclei move according to the classical equations of motion in response to this quantal force. In addition, pair potentials basedmore » on Thomas-Fermi models (Moliere) extend both the temperature and density range of the more sophisticated models. Comparisons of the models are presented together with a comprehensive description of the techniques. Examples over a broad temperature and density range illustrate the basic physics for a hot, dense hydrogen medium. (c) 1995 The American Physical Society« less
  • An extended first-principles molecular dynamics (FPMD) method based on Kohn-Sham scheme is proposed to elevate the temperature limit of the FPMD method in the calculation of dense plasmas. The extended method treats the wave functions of high energy electrons as plane waves analytically and thus expands the application of the FPMD method to the region of hot dense plasmas without suffering from the formidable computational costs. In addition, the extended method inherits the high accuracy of the Kohn-Sham scheme and keeps the information of electronic structures. This gives an edge to the extended method in the calculation of mixtures ofmore » plasmas composed of heterogeneous ions, high-Z dense plasmas, lowering of ionization potentials, X-ray absorption/emission spectra, and opacities, which are of particular interest to astrophysics, inertial confinement fusion engineering, and laboratory astrophysics.« less
