【 摘 要 】

We propose an energy relaxation mechanism whereby strongly correlated spin systems decay into their ground states. The relaxation is driven by cavity quantum electrodynamics interaction and the decay of cavity photons, It is shown that by applying broadband driving fields, strongly correlated systems can be cooled regardless of the specific details of their energy level profiles. The scheme would also have significant implications in other contexts, such as adiabatic quantum computation and steady-state entanglement in dissipative systems. (C) 2014 Elsevier B.V.
