Dynamic screening of an ion in a degenerate electron gas within the second-order Born approximation
Hrachya B. Nersisyan, José M. Fernández-Varea, Néstor R. Arista
The dynamic Friedel sum rule (FSR) is derived within the second-order Born (B2) approximation for an ion that moves in a fully degenerate electron gas and for an arbitrary spherica…
Stopping of a relativistic electron beam in a plasma irradiated by an intense laser field
Hrachya B. Nersisyan, Claude Deutsch
The effects of a radiation field (RF) on the interaction process of a relativistic electron beam (REB) with an electron plasma are investigated. The stopping power of the test elec…
Dielectric function of a collisional plasma for arbitrary ionic charge
H. B. Nersisyan, M. E. Veysman, N. E. Andreev +1
A simple model for the dielectric function of a completely ionized plasma with an arbitrary ionic charge, that is valid for long-wavelength high-frequency perturbations is derived…
Second-order Born approximation for the scattering phase shifts: Application to the Friedel sum rule
Hrachya B. Nersisyan, José M. Fernández-Varea
Screening effects are important to understand various aspects of ion-solid interactions and, in particular, play a crucial role in the stopping of ions in solids. In this paper the…
Resistive MHD model for cylindrical plasma expansion in a magnetic field
H. B. Nersisyan, K. A. Sargsyan, D. A. Osipyan +1
The study of hot plasma expansion in a magnetic field is of interest for many laboratory and astrophysical applications. In this paper, an exactly solvable analytical model is prop…
An exact solution of the moving boundary problem for the relativistic plasma expansion in a dipole magnetic field
H. B. Nersisyan, K. A. Sargsyan, D. A. Osipyan +1
An exact analytic solution is obtained for a uniformly expanding, neutral, highly conducting plasma sphere in an ambient dipole magnetic field with an arbitrary orientation of the…
