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…
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…
Cosmologial magnetic field amplification around z~100
Esteban A. Calzetta, Alejandra Kandus
We study the corrections to the conformal evolution of primordial magnetic fields after recombination, produced by the fall of the ionized fraction of matter into the dark matter g…
