• Authors: Francesca Fassioli, Jerome Faist, Martin Eckstein, Daniele Fausti
• Abstract summary: We develop a formalism to describe the cavity mediated energy exchange between a material and its electromagnetic environment. We show that coplanar cavities can significantly affect the heat load on the sample if the cavity resonance lies within the frequency region where free-space radiative heat dominates.

• Abstract: Cavity electrodynamics is emerging as a promising tool to control chemical processes and quantum material properties. In this work we develop a formalism to describe the cavity mediated energy exchange between a material and its electromagnetic environment. We show that coplanar cavities can significantly affect the heat load on the sample if the cavity resonance lies within the frequency region where free-space radiative heat dominates, typically the mid-IR at ambient temperature, while spectral filtering is necessary for having an effect with lower frequency cavities.

  Cavity quantum electrodynamics (C-QED) effects have been demonstrated with nitrogen vacancy center spins in diamond in microwave resonators at cryogenic temperature. We show the possibility to realize strong collective coupling and the resulting C-QED effects with ensembles of spins at room temperature.

  We show that it is possible to observe the quantum nature of strong coupling even at finite temperatures, and to exploit this coupling to permit cooling of the thermal microwave mode towards the ground-state. Cooling for multiple atoms is also explored, showing maximal cooling for small samples, making this a viable approach to cavity cooling with potential applications in long-range coupling of superconducting qubits via thermal waveguides.
