“…From this very general findings it can be understood that in (Zhu and Fan, 2014) it was necessary to consider three non-reciprocal thermal emitters to show that detailed balance can be broken for thermal radiation and in (Zhu and Fan, 2016) it was necessary to consider three non-reciprocal nanoparticles to observe the persistent heat current. On the other hand, it is also clear that the heat exchange between two non-reciprocal halfspaces will not show any rectification effect (Fan et al, 2020;Moncada-Villa et al, 2015). On the other hand, when considering two objects with an environment, then the environment can be regarded as a third object.…”

Many-body physics aims to understand emergent properties of systems made of many interacting objects. This article reviews recent progress on the topic of radiative heat transfer in many-body systems consisting of thermal emitters interacting in the near-field regime. Near-field radiative heat transfer is a rapidly emerging field of research in which the cooperative behavior of emitters gives rise to peculiar effects which can be exploited to control heat flow at the nanoscale. Using an extension of the standard Polder and van Hove stochastic formalism to deal with thermally generated fields in N -body systems, along with their mutual interactions through multiple scattering, a generalized Landauer-like theory is derived to describe heat exchange mediated by thermal photons in arbitrary reciprocal and non-reciprocal multi-terminal systems. In this review, we use this formalism to address both transport and dynamics in these systems from a unified perspective. Our discussion covers: (i) the description of non-additivity of heat flux and its related effects, including fundamental limits as well as the role of nanostructuring and material choice, (ii) the study of equilibrium states and multistable states, (iii) the relaxation dynamics (thermalization) toward local and global equilibria, (iv) the analysis of heat transport regimes in ordered and disordered systems comprised of a large number of objects, density and range of interactions, and (v) the description of thermomagnetic effects in magneto-optical systems and heat transport mechanisms in non-Hermitian many-body systems. We conclude this review by listing outstanding challenges and promising future research directions.

“…A first statement about forces in this geometry follows from a property of the heat flux S(k y ): As shown in Ref. [33] by explicit manipulations of Eq. ( 9), S(k y ) is symmetric in k y if the two plates are made of reciprocal materials, even if the reciprocal materials are described by a tensorial ε.…”

The Casimir effect describes the normal force between two parallel plates, due to fluctuations of the electromagnetic field. We show that smooth plates may also exert lateral forces if they are at different temperatures, and at least one plate is made of a nonreciprocal material. The ratio of the lateral force to heat transfer is surprisingly large in the near field regime, diverging inversely with the separation d. A heat engine can use this force to move a plate with velocity v. An Onsager symmetry, which we extend to non-reciprocal plates, limits the engine efficiency by the Carnot value, ηc. The optimal velocity of operation in the far field is of the order of cηc, where c is the speed of light. In the near field regime, this velocity can be reduced to order of ωdηc, where ω is a typical material frequency.

“…There has been great interest and numerous theoretical proposals for nonreciprocal absorbers on the grounds that they do not obey the Kirchhoff thermal radiation law (1)(2)(3)(4). Interest in this phenomenon stems from fundamental considerations and applications ranging from infrared (IR) spectroscopy, sensing, and thermal energy conversion efficiency (5,6). For IR sensing applications, the amount of light absorbed in each channel is something that could be controlled in a nonreciprocal device, where the absorptivity can be tuned from strong in one channel and weak in another and vice versa (7,8).…”

Nonreciprocal elements are a vital building block of electrical and optical systems. In the infrared regime, there is a particular interest in structures that break reciprocity because their thermal absorptive (and emissive) properties should not obey the Kirchhoff thermal radiation law. In this work, we break time-reversal symmetry and reciprocity in n-type–doped magneto-optic InAs with a static magnetic field where light coupling is mediated by a guided-mode resonator structure, whose resonant frequency coincides with the epsilon-near-zero resonance of the doped indium arsenide. Using this structure, we observe the nonreciprocal absorptive behavior as a function of magnetic field and scattering angle in the infrared. Accounting for resonant and nonresonant optical scattering, we reliably model experimental results that break reciprocal absorption relations in the infrared. The ability to design these nonreciprocal absorbers opens an avenue to explore devices with unequal absorptivity and emissivity in specific channels.
