  1. 39. The problem of radiation reaction in intense laser fields
    Prof. Hartmut Ruhl (LMU)
    30.01.20, 17:00
    It is well-known that interacting fields pose fundamental problems. A prototypical example is radiation reaction. The well-known LAD equation in the context are of little use since they are ill-defined. Up to now it is not fully clear how to derive consistent equations of motion for interacting fields. We propose to give up the notion that electrons are point-like or in other words are...

  2. 55. Two-dimensional energy and carrier diffusion in silicon upon X-ray irradiation or swift heavy ion impact
    Dr. Vladimir Lipp (CFEL, DESY)
    30.01.20, 17:30
    We present the dynamics of carrier density and carrier/atomic energy in silicon after its excitation by an X-ray laser or swift heavy ion in two-dimensional geometry. The dynamics is modeled using the so-called nTTM model, i.e., a system of three coupled partial differential equations: one for carrier ambipolar diffusion and two coupled diffusion equations for carriers and phonons. To solve...

  3. 38. Equation of state for vanadium at high energy densities
    Dr. Konstantin Khishchenko (Joint Institute for High Temperatures RAS)
    30.01.20, 17:55
    A new semiempirical equation of state for vanadium is proposed with taking into account melting and evaporation effects. Calculations of thermodynamic characteristics and the phase boundaries of solid, liquid and vapor over a wide range of densities and temperatures are carried out. Comparison of calculated results with available experimental data and theoretical predictions at high energy...

  4. 47. Quantum statistical operator approach to optical properties of metallic and classical plasmas
    Dr. Mikhail Veysman (JIHT RAS)
    30.01.20, 18:20
    Hydrodynamic simulations of action of intense energy fluxes on metals requires knowledge of their kinetic coefficients in a wide range of temperatures and densities, and taking into account the recent progress in powerfull short-wavelength laser systems, also in a wide range of frequencies. The quantum-statistical operator method and linear response theory allow to express kinetic coefficients...

  5. 53. Ionization in high-density plasmas: an ab initio study for carbon at Gbar pressures
    Prof. Gerd Roepke (Universitaet Rostock, Institut fuer Physik)
    30.01.20, 18:45
    We apply density functional theory molecular dynamics (DFT-MD) simulations to calculate the ionization degree of plasmas in the warm dense matter regime. Standard descriptions of the ionization potential depression (IPD) have been challenged recently by experiments approaching unprecedentedly high densities indicating that improved IPD models are required to describe warm dense matter. We...
