The large expansion for a half-filled asymmetric Hubbard model on a triangular ladder in the presence of spin-dependent magnetic flux
Shota Garuchava, Bachana Beradze, Tatia Sharia +1
We consider a half-filled system of spin-1/2 fermions on a triangular ladder with spin-dependent hopping in the presence of spin-dependent flux. Using the Schrieffer-Wolff transfor…
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…
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…
Sign singularity of the local energy transfer in space plasma turbulence
Luca Sorriso-Valvo, Gaetano De Vita, Federico Fraternale +18
In weakly collisional space plasmas, the turbulent cascade provides most of the energy that is dissipated at small scales by various kinetic processes. Understanding the characteri…
Overstability of acoustic waves in strongly magnetized anisotropic MHD shear flows
E. S. Uchava, B. M. Shergelashvili, A. G. Tevzadze +1
We present a linear stability analysis of the perturbation modes in anisotropic MHD flows with velocity shear and strong magnetic field. Collisionless or weakly collisional plasma…
Revisiting linear dynamics of non-axisymmetric perturbations in weakly magnetized accretion discs
G. R. Mamatsashvili, G. D. Chagelishvili, G. Bodo +1
We investigate linear dynamics of non-axisymmetric perturbations in incompressible, vertically stratified Keplerian discs with a weak vertical magnetic field in the shearing box ap…
On the puzzling feature of the silence of precursory electromagnetic emissions
K. Eftaxias, S. M. Potirakis, T. Chelidze
It has been suggested that fracture-induced MHz-kHz electromagnetic (EM) emissions, which emerge from a few days up to a few hours before the main seismic shock occurrence permit a…
In connection with identification of VLF emissions before L'Aquila earthquake
M. Kachakhidze, Z. Kereselidze, N. Kachakhidze
The present paper deals with an attempt to check up the theoretical model of self-generated seismo-electromagnetic oscillations of LAI system on the basis of retrospective data. Ap…
Linear coupling of modes in 2D radially stratified astrophysical discs
A. G. Tevzadze, G. D. Chagelishvili, G. Bodo +1
We investigate mode coupling in a two dimensional compressible disc with radial stratification and differential rotation. We employ the global radial scaling of linear perturbation…
