A conserved thermo-mechanic invariant in extended fluid description of collisionless plasmas

E. S. Uchava, A. G. Tevzadze

We investigate linear perturbations of an incompressible, weakly collisional, anisotropic plasma in the low frequency limit using an extended 16-moment fluid description that retai…

Electromagnetic vortex beam dynamics in degenerate electron-positron astrophysical plasmas

V. I. Berezhiani, Z. N. Osmanov, S. V. Mikeladze

For degenerate astrophysical electron-positron plasmas we have considered dynamics of electromagnetic beams carrying angular momentum. It is found for arbitrary level of degeneracy…

Solitary structure formation and self-guiding of electromagnetic beam in highly degenerate electron plasma

V. I. Berezhiani, Z. N. Osmanov, S. M. Mahajan +1

In the present paper we consider the nonlinear interaction of high frequency intense electromagnetic (EM) beam with degenerate electron plasmas. In a slowly varying envelop approxi…

Fire-hose instability of inhomogeneous plasma flows with heat fluxes

E. S. Uchava, A. G. Tevzadze, B. M. Shergelashvili +2

We study the effects of heat flows and velocity shear on the parallel firehose instability in weakly collisional plasma flow. For this purpose we apply an anisotropic 16-moments MH…

Linking dissipation-induced instabilities with nonmodal growth: the case of helical magnetorotational instability

George Mamatsashvili, Frank Stefani

The helical magnetorotational instability is known to work for resistive rotational flows with comparably steep negative or extremely steep positive shear. The corresponding lower…

Nonlinear transverse cascade and two-dimensional magnetohydrodynamic subcritical turbulence in plane shear flows

G. R. Mamatsashvili, D. Z. Gogichaishvili, G. D. Chagelishvili +1

We find and investigate via numerical simulations self-sustained two-dimensional turbulence in a magnetohydrodynamic flow with a maximally simple configuration: plane, noninflectio…

Nature and dynamics of overreflection of Alfven waves in MHD shear flows

D. Gogichaishvili, G. Chagelishvili, R. Chanishvili +1

Our goal is to gain new insights into the physics of wave overreflection phenomenon in MHD nonuniform/shear flows changing the existing trend/approach of the phenomenon study. The…

Weak and strong regimes of incompressible magnetohydrodynamic turbulence

G. Gogoberidze, S. M. Mahajan, S. Poedts

It is shown that in the framework of the weak turbulence theory, the autocorrelation and cascade timescales are always of the same order of magnitude. This means that, contrary to…

On linear coupling of acoustic and cyclotron waves in plasma flows

Andria Rogava, Grigol Gogoberidze

It is found that in magnetized electrostatic plasma flows the velocity shear couples ion-acoustic waves with ion-cyclotron waves and leads, under favorable conditions, to their eff…
