Quark mass dependence of the vacuum electric conductivity induced by the magnetic field in SU(2) lattice gluodynamics
the vacuum electric conductivity induced the magnetic field in SU(2) lattice gluodynamics
2011/1/6
We study the electric conductivity of the vacuum of quenched SU(2) lattice gauge theory induced by the magnetic field B as a function of the bare quark mass m. The conductivity grows as the quark mass...

Proof of universality of electrical conductivity at finite chemical potential
electrical conductivity finite chemical potential
2010/12/23
It was proposed in arXiv:1008.2944 that, for certain gauge theories with gravity duals, electrical conductivity at finite chemical potential is universal. Here we provide a general proof that, when m...
