A Quantum Heat Exchanger for Nanotechnology [PDF]

open access: yesEntropy, 2020
In this paper, we design a quantum heat exchanger which converts heat into light on relatively short quantum optical time scales. Our scheme takes advantage of heat transfer as well as collective cavity-mediated laser cooling of an atomic gas inside a cavitating bubble.
