Electrical conductivity of quark matter in magnetic field

TL;DR

This paper discusses the electrical conductivity of quark matter in magnetic fields, suggesting it may be independent of magnetic field direction and strength, which challenges common assumptions.

Contribution

It proposes that quark matter conductivity can be unaffected by magnetic field orientation and magnitude, offering a new perspective on the Chiral Magnetic Effect.

Findings

Conductivity may be independent of magnetic field direction.

Conductivity may not be proportional to magnetic field strength.

Challenges existing assumptions about magnetic field influence.

Abstract

Fermion currents in dense quark matter embedded into magnetic field are under intense discussions motivated by Chiral Magnetic Effect. We argue that conductivity of quark matter may be independent of the magnetic field direction and not proportional to the magnetic field strength.
