热场动力学中的原子辐射跃迁

Atomic Radiative Transitions in Thermo Field Dynamics

J. L. Tomazelli, L. C. Costa

摘要:

在这项工作中,我们重新推导了原子电子在热辐射存在下的Lamb-Retherford能移。利用Dalibard,Dupont-Roc和Cohen-Tannoudji(DDC)形式,将物理量表示为合适的统计函数的卷积,构造了库仑规范下热场动力学的电磁场传播子,以研究有限温度对原子能级的影响.在同样的背景下,我们也分析了基态稳定性问题。

英文摘要:

In this work we rederive the Lamb-Retherford energy shift for an atomic electron in the presence of a thermal radiation. Using the Dalibard, Dupont-Roc and Cohen-Tannoudji (DDC) formalism, where physical observables are expressed as convolutions of suitable statistical functions, we construct the electromagnetic field propagator of Thermo Field Dynamics in the Coulomb gauge in order to investigate finite temperature effects on the atomic energy levels. In the same context, we also analyze the problem of the ground state stability.
