Spectral decoherence without depolarization in curvature radiation
A. G. Tevzadze, N. L. Shatashvili
Context: Fast radio bursts often exhibit strong linear polarization together with pronounced spectral structure. Yet in coherent curvature radiation, spectral decoherence and depol…
Spectral Universality of Turbulent Fluctuations in Relativistic Flows
Alexander G. Tevzadze
We develop a Lorentz-covariant framework for projecting spacetime spectra into temporal spectra of stationary turbulent fluctuations in relativistic flows. For self-similar spaceti…
Irreversibility and Entropy Exclusion in Collisionless Plasmas
Alexander G. Tevzadze
We examine entropy production in reduced descriptions of collisionless plasmas. Introducing a closure dependent entropy hierarchy, we show that non-conservative moment closures gen…
On Lorentz Variability of Magnetically Dominated Relativistic Outflows
V. I. Berezhiani, N. L. Shatashvili, A. G. Tevzadze
We show that magnetized relativistic outflows can exhibit a relativistic effect in which Lorentz transformation maps spatially extended magnetic field structure into apparent tempo…
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…
