A 89 (4) (April). doi:10.1103/physreva.89.042117.1050-2947http://nrs.harvard.edu/urn-3:HUL.InstRepos:16883009When a quantum system interacts with multiple reservoirs, the environmental effects are usually treated in an additive manner. We show that this assumption breaks down for non-Markovian environments that have finite memory times. Specifically, we demonstrate that quantum interferences between independent environments can qualitatively modify the dynamics of the physical system. We illustrate this effect with a two-level system coupled to two structured photonic reservoirs, discuss its origin using a nonequilibrium diagrammatic technique, and show an example when the application of this interference can result in an improved dark state preparation in a Λ system.en-USJournal Article2015-06-2910.1103/PhysRevA.89.042117
