# Strong coupling and active cooling in a finite-temperature hybrid atom-cavity system

@article{Keary2022StrongCA, title={Strong coupling and active cooling in a finite-temperature hybrid atom-cavity system}, author={Lindsey Keary and Jonathan D. Pritchard}, journal={Physical Review A}, year={2022} }

For a standard two-level atom coupled to the quantized ﬁeld of a resonant cavity, ﬁnite temperature effects lead to thermal occupation of the cavity modes that obfuscates measurement of the quantum nature of the atom-light interaction. In this paper we demonstrate that using a hybrid system of a superconducting cavity coupled to a multi-level Rydberg atom it is possible to observe the quantum nature of strong coupling even at ﬁnite temperatures, and to exploit this coupling to permit cooling of…
