Electrical Conductivity of Dense Quark Matter with Fluctuations and Magnetic Field Included

Abstract

We investigate the electrical conductivity(EC) of dense quark matter in the vicinity of the phase transition line. We show that: (i) At high density the Drude EC does not depend on the magnetic field up to $eB\sim 10^{19}G$. (ii) In the precritical region the fluctuation EC (paraconductivity) dominates over the Drude one.
