Chiral magnetic effect for chiral fermion system

Understand

We concisely derive chiral magnetic effect through Wigner function approach for chiral fermion system.

• Then we derive chiral magnetic effect through solving the Landau levels of chiral fermions in detail.
• The procedures of second quantization and ensemble average lead to the equation of chiral magnetic effect for righthand and lefthand fermion systems.
• Chiral magnetic effect only comes from the contribution of the lowest Landau level.
