  1. 5. Geometrical effects on hydrodynamic instabilities in high energy density matters
    Herr Yuanbo Sun (Beijing institute of Technology)
    28.01.20, 17:00
    Talk
    we derived the dispersion relation for the RTI problem at cylindrical fluid/fluid, solid/solid and fluid/solid interfaces by the decomposition method and also its planar counterpart, which is still easily expanded to study the behaviors of the interfaces by the impulsively accelerated model. Searching for the mathematical details of the dispersion relation, we developed a methodology to study...

  2. 2. Stability boundaries for the Rayliegh-Taylor instability in elastic-plastic solid slabs
    Prof. Antonio Roberto Piriz (University of Castilla-La Mancha)
    28.01.20, 17:25
    Talk
    The linear theory of the incompressible Rayleigh-Taylor instability in elastic-plastic solid slabs is developed on the basis of the simplest constitutive model consisting in a linear elastic (Hookean) initial stage followed by a rigid-plastic phase. The slab is under the action of a constant acceleration and it overlays a very thick ideal fluid. The boundaries of stability and plastic flow are...

  3. 12. Recent advances in research of underwater electrical explosion of wires and shock waves generation
    Prof. Yakov Krasik (Physics Department, Technion)
    28.01.20, 17:50
    Talk
    Experimental and numerical data regarding recent results on underwater electrical explosion of wires and shock waves generation will be presented which include ultra-fast Al wire combustion, development of thermal instabilities during wire explosion and symmetry of converging shock waves.

  4. 1. Density jump as a function of magnetic field for collisionless shocks in pair plasmas: The perpendicular case
    Dr. Antoine Bret (Universidad Castilla La Mancha)
    28.01.20, 18:15
    Talk
    We extend the analysis presented last year to the perpendicular case.

  5. 31. Non-adiabatic effects and exciton-like states during insulator-to-metal transition in warm dense hydrogen
    Dr. Vladimir Stegailov (JIHT RAS)
    28.01.20, 18:40
    Talk
    Transition of molecular hydrogen to atomic ionized state with increase of temperature and pressure poses still unresolved problems for experimental methods and theory. Here we analyze the dynamics of this transition and show its nonequilibrium non-adiabatic character overlooked in both interpreting experimental data and in theoretical models. The non-adiabatic mechanism explains the strong...
