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

Understand

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.
