Chiral Magnetic Effect on the Lattice

Understand

We review recent progress on the lattice simulations of the chiral magnetic effect.

• There are two different approaches to analyze the chiral magnetic effect on the lattice.
• In one approach, the charge density distribution or the current fluctuation is measured under a topological background of the gluon field.
• In the other approach, the topological effect is mimicked by the chiral chemical potential, and the induced current is directly measured.
