磁化手性非对称QED物质中的费米子自能

Fermion self-energy in magnetized chirally asymmetric QED matter

D. O. Rybalka

摘要:

本文计算了具有手征化学势的冷QED等离子体在磁场中的费米子自能。研究发现,在这种等离子体中动态产生的动量位移参数导致手征磁效应电流的修正。我们认为,在早期宇宙中的手征非对称原始等离子体中,动量位移参数可能与磁场的演化有关。

英文摘要:

The fermion self-energy is calculated for a cold QED plasma with chiral chemical potential in a magnetic field. It is found that a momentum shift parameter dynamically generated in such a plasma leads to a modification of the chiral magnetic effect current. It is argued that the momentum shift parameter can be relevant for the evolution of magnetic field in the chirally asymmetric primordial plasma in the early Universe.
