“…[13][14][15] The phonon coupling in electric fields contributes to phonon transmission between two solids when gap distance D o 5 nm. 16,17 Moreover, Fong et al found Casimir heat transfer between two Si 3 N 4 membranes when D o 400 nm, 18 and they proposed that this phenomenon can be applied in quantum thermal machines. 19 In a previous study, a new heat transfer mechanism named quasi-Casimir heat transfer was proposed across a vacuum gap of D o 1 nm in the absence of electromagnetic fields with the aid of molecular interactions between two solid walls.…”

“…The theory has been applied to a variety of situations and geometries (Krüger et al, 2011;Otey et al, 2014;Tang et al, 2021) and has been reviewed extensively (Basu et al, 2009;Biehs et al, 2021;Bimonte et al, 2017;Henkel, 2017;Joulain et al, 2005;Song et al, 2015;Volokitin and Persson, 2007). Recent experiments (Kim et al, 2015;Kittel et al, 2005;Ottens et al, 2011;Shen et al, 2009) mostly confirm the theory, but there remain some controversies (Cui et al, 2017;Kloppstech et al, 2017;Tokunaga et al, 2021). An interesting recent development is the super-Planckian heat transport (Cuevas, 2019;Fernández-Hurtado et al, 2018), e.g., two sheets side by side instead of face to face, where it is found that the enhancement of transport occurs even for the far field (Thompson et al, 2018).…”

We review the description and modeling of transport phenomena among the electron systems coupled via scalar or vector photons. It consists of three parts. The first part is about scalar photons, i.e., Coulomb interactions. The second part is with transverse photons described by vector potentials. The third part is on φ = 0 or temporal gauge, which is a full theory of the electrodynamics. We use the nonequilibrium Green's function (NEGF) formalism as a basic tool to study steady-state transport. Although with local equilibrium it is equivalent to the fluctuational electrodynamics (FE), the advantage of NEGF is that it can go beyond FE due to its generality. We have given a few examples in the review, such as transfer of heat between graphene sheets driven by potential bias, emission of light by a double quantum dot, and emission of energy, momentum, and angular momentum from a graphene nanoribbon. All of these calculations are based on a generalization of the Meir-Wingreen formula commonly used in electronic transport in mesoscopic systems, with materials properties represented by photon self-energy, coupled with the Keldysh equation and the solution to the Dyson equation.
