Generalized Ohm's law for relativistic plasmas
Alejandra Kandus, Christos G. Tsagas
We generalise the relativistic expression of Ohm's law by studying a multi-fluid system of charged species using the 1+3 covariant formulation of general relativistic electrodynami…
Analysis of the Effect of a Mean Velocity Field on Mean Field Dynamo
Alejandra Kandus
We study semi-analytically and in a consistent manner, the generation of a mean velocity field by helical MHD turbulence, and the effect that this field can have…
On the mean field dynamo with Hall effect
A. Kandus, M. J. Vasconcelos, A. H. Cerqueira
We study in the present paper how Hall effect modifies the quenching process of the electromotive force (e.m.f.) in Mean Field Dynamo (MFD) theories. We write down the evolution eq…
Superadiabatic-type magnetic amplification in conventional cosmology
Christos G. Tsagas, Alejandra Kandus
We consider the evolution of cosmological magnetic fields in FRW models and outline a geometrical mechanism for their superadiabatic amplification on large scales. The mechanism op…
Origin of coherent magnetic fields in high redshift objects
A. Kandus, R. Opher, S. R. M. Barros
Large scale strong magnetic fields in galaxies are generally thought to have been generated by a mean field dynamo. In order to have generated the fields observed, the dynamo would…
Dependence of the MHD shock thickness on the finite electrical conductivity
A. Kandus, R. Opher
The results of MHD plane shock waves with infinite electrical conductivity are generalized for a plasma with a finite conductivity. We derive the adiabatic curves that describe the…
