【摘要】 本文讨论了规范理论中红外极限下的Plasma效应,具体计算了QED中光子真空极化在温度T≠0,化学势μ≠0时单圈近似,发现只有电场对规范玻色子的质量有贡献,磁场则没有贡献。更多还原

【Abstract】 The plasma effects of gauge theories are investigated and the one-loop contribu-tions to self-energy part of the photon at T≠0 and μ≠0 are calculated. It is shownthat only electric fields give photon an effective mass, but magnetic fields don’t contri-bute.更多还原
