Chiral magnetic effect in lattice QCD with a chiral chemical potential
read the original abstract
We perform a first lattice QCD simulation including two-flavor dynamical fermion with a chiral chemical potential. Because the chiral chemical potential gives rise to no sign problem, we can exactly analyze a chirally imbalanced QCD matter by the Monte Carlo simulation. By applying an external magnetic field to this system, we obtain a finite induced current along the magnetic field, which corresponds to the chiral magnetic effect. The obtained induced current is proportional to the magnetic field and to the chiral chemical potential, which is consistent with an analytical prediction.

Chiral Magnetic Effect and Negative Magnetoresistance across the phase diagram of finite-density SU(2) gauge theory
In SU(2) lattice QCD at finite density, the chiral magnetic effect from axial-vector correlators remains close to the free massless quark value with weak T and mu dependence in the plasma, while negative magnetoresist...

Chiral Magnetic effect as the anomaly in the transverse axial vector Ward Identity
The chiral magnetic effect is the anomaly of the transverse axial vector Ward identity, which enforces a universal conductivity of 1/(2π²) robust against external parameters and interactions.
