### Physics of relativistic collisionless shocks: The scattering-center frame

Wed, 07/17/2019 - 10:00

Author(s): Guy Pelletier, Laurent Gremillet, Arno Vanthieghem, and Martin Lemoine

In this first paper of a series dedicated to the microphysics of unmagnetized, relativistic collisionless pair shocks, we discuss the physics of the Weibel-type transverse current filamentation instability that develops in the shock precursor, through the interaction of an ultrarelativistic suprathe...

Author(s): Yongjun Choi, Gautham Dharuman, and Michael S. Murillo

The dynamic structure factor (DSF) of the Yukawa system is here obtained with highly converged molecular dynamics (MD) over the entire liquid phase. The data provide a rigorous test of theoretical models of ion-acoustic wave-dispersion relations, the intermediate scattering function, and the high-fr...

### Kinetic plasma waves carrying orbital angular momentum

Mon, 07/15/2019 - 10:00

Author(s): D. R. Blackman, R. Nuter, Ph. Korneev, and V. T. Tikhonchuk

The structure of Langmuir plasma waves carrying a finite orbital angular momentum is revised in the paraxial approximation. It is shown that the kinetic effects related to higher-order momenta of the electron distribution function lead to coupling of Laguerre-Gaussian modes and result in a modificat...

### Topology and stochasticity of turbulent magnetic fields

Mon, 07/08/2019 - 10:00

Author(s): Amir Jafari and Ethan Vishniac

We present a mathematical formalism for the topology and stochasticity of vector fields based on renormalization group methodology. The concept of a scale-split energy density, ψl,L=Bl·BL/2 for vector field B(x,t) renormalized at scales l and L, is introduced in order to quantify the notion of the f...

Mon, 07/08/2019 - 10:00

Author(s): Hai P. Le, Mark Sherlock, and Howard A. Scott

This paper describes a computational model that self-consistently combines physics of kinetic electrons and atomic processes in a single framework. The formulation consists of a kinetic Vlasov-Boltzmann-Fokker-Planck equation for free electrons and a non-Maxwellian collisional-radiative model for at...

Author(s): Damian C. Swift, Thomas Lockard, Richard G. Kraus, Lorin X. Benedict, Philip A. Sterne, Mandy Bethkenhagen, Sebastien Hamel, and Bard I. Bennett

Recent path-integral Monte Carlo and quantum molecular dynamics simulations have shown that computationally efficient average-atom models can predict thermodynamic states in warm dense matter to within a few percent. One such atom-in-jellium model has typically been used to predict the electron-ther...

### Three-wave interactions in magnetized warm-fluid plasmas: General theory with evaluable coupling coefficient

Fri, 06/28/2019 - 10:00

Author(s): Yuan Shi

Resonant three-wave coupling is an important mechanism via which waves interact in a nonlinear medium. When the medium is a magnetized warm-fluid plasma, a previously unknown formula for the coupling coefficients is derived by solving the fluid-Maxwell's equations to second order using multiscale pe...

Author(s): Fernando Haas

We set up a proposal to extend significantly recent works on neutrino-plasma interaction, allowing the possibility of deep degenerate and relativistic electrons, which are often present in compact stars such as high-density white dwarfs. The methodology involves the covariant hydrodynamic formulatio...

Author(s): A. Diaw and Michael S. Murillo

Nonideal plasmas have nontrivial space and time correlations, which simultaneously impact both the excess thermodynamic quantities as well as the collision processes. However, hydrodynamics models for designing and interpreting nonideal plasma experiments, such as inertial-confinement fusion experim...

Author(s): V. Vekselman, Y. Raitses, and M. N. Shneider

Coagulation growth kinetics of nanoparticles in plasma is affected by interparticle electrostatic forces due to the charging phenomenon. In stationary plasmas, unipolar charging of particles results in retardation of particle growth and may result in a limitation on particle size. We demonstrate the...

Author(s): A. F. A. Bott and G. Gregori

We calculate the Thomson scattering cross section in a nonrelativistic, magnetized, high-density plasma—in a regime where collective excitations can be described by magnetohydrodynamics. We show that, in addition to cyclotron resonances and an elastic peak, the cross section exhibits two pairs of pe...
