From: Effect of Time-Delayed Feedback on the Interaction of a Dimer System with its Environment

(a) The two interacting TLS (top) and their effective modeling (bottom) as a single two-level system, with |e 1〉, |g 1〉 and |e 2〉, |g 2〉 the excited and ground states of the two TLS, respectively. (b) Scheme of the interaction between the system and the environment, showing the delay τ and the interaction strength constant γ 0.
