Corrections from space-time dependent electromagnetic fields to Wigner functions and spin polarization
Shi-Zheng Yang, Jian-Hua Gao, Shi Pu
We have derived the Wigner equations at global equilibrium with constant vorticity but space-time dependent electromagnetic fields up to second order in semiclassical expansion. We…

Second-order chiral kinetic theory from Wigner function approach
Shi-Zheng Yang, Shu-Xiang Ma, Jian-Hua Gao
We present a systematic method to derive the chiral kinetic theory from the Wigner equations based on quantum field theory order by order. We take special effort to derive the chir…
