Causality and Atomic Dynamics in the Fermi Problem
We consider the so-called Fermi problem, that is the problem of causality in the interaction of a pair of two-level atoms with the quantum electromagnetic field H. Investigation of relativistic causality in this system has been the subject of several papers until very recently (2).
