In recent years there has been great interest towards optical cavities as a tool to manipulate the properties and phases of embedded quantum materials. Due to the Purcell effect, a cavity changes the photon phase space and thus the rate of electromagnetic transitions within the material, modifying the exchange rate of heat radiation with the photon environment. This work derives a simple expression for the radiative heat absorbed by the material, investigates how it changes in the presence of a cavity, and shows that it is enhanced dramatically for appropriate cavity geometries. This effect is compared with typical energy dissipation processes, providing a criterion to estimate its impact on the temperature of a material in the cavity and applying it to 1T-TaS2.

Abstract
In recent years there has been great interest towards optical cavities as a tool to manipulate the properties and phases of embedded quantum materials. Due to the Purcell effect, a cavity changes the photon phase space and thus the rate of electromagnetic transitions within the material, modifying the exchange rate of heat radiation with the photon environment. This work derives a simple expression for the radiative heat absorbed by the material, investigates how it changes in the presence of a cavity, and shows that it is enhanced dramatically for appropriate cavity geometries. This effect is compared with typical energy dissipation processes, providing a criterion to estimate its impact on the temperature of a material in the cavity and applying it to 1T-TaS2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
