Black-body radiation shift of atomic energy-levels:The $(Z\alpha {)}^2\alpha T^2/m$ correction

Wanping Zhou, Xuesong Mei, Jingjun Lu +1

The next-to-leading order black-body radiation(BBR) shift to atomic energy-levels, namely $(Z\alpha {)}^2\alpha T^2/m$ correction, was studied by using the nonrelativistic quantum electrodynam…
