Signature of resonant modes in radiative heat current noise spectrum

  author={Jonathan L. Wise and N. Roubinowitz and Wolfgang Belzig and D M Basko},
Radiative heat transfer between bodies is often dominated by a narrow resonance in the transmission, e. g. due to a cavity mode or a surface excitation. However, this resonant character is not visible in the average heat current. Here, we show that the noise spectrum of heat current can serve as a direct probe of the heat-carrying excitations. Namely, the resonant mode produces a sharp peak in the noise spectrum with a width related to the mode lifetime. We demonstrate that heat transfer in…
