标题： Scattering approach to near-field radiative heat transfer

摘要： 我们为线性电路中近场辐射热传递问题构建了一个有效的量子散射理论。 从与半经典涨落电磁理论相同的要素构建，这是处理该问题的标准工具，我们的构造使能够计算能量电流的任意关联函数，而涨落电磁理论只能用于平均电流。 我们给出了能量电流涨落的一般表达式，并表明它具有一个重要的非耗散贡献，在有限频率噪声中可能占主导地位，而在平均电流中则不存在。 显示英文摘要

摘要： We formulate an effective quantum scattering theory for the problem of near-field radiative heat transfer in linear electric circuits. Built from the same ingredients as the semiclassical fluctuational electrodynamics, the standard tool to handle this problem, our construction enables one to calculate arbitrary correlation functions of the energy current, while the fluctuational electrodynamics can be used only for the average current. We give a general expression for the energy current fluctuations in terms of the circuit's scattering matrix and show that it has an important non-dissipative contribution that can dominate the finite-frequency noise while being absent in the average current.
