“…Investigations of rectifiers have been done also at the quantum level using other energy carriers such as photons [10], electrons [11][12][13] and spins [14][15][16][17][18][19][20][21]. In [17,18], asymmetric quantum structures and hybrid material junctions are identified as the main ingredients for thermal rectification.…”

We study the rectification of heat current in an XXZ chain segmented in two parts. We model the effect of the environment with Lindblad heat baths. We show that, in our system, rectification is large for strong interactions in half of the chain and if one bath is at cold enough temperature. For the numerically accessible chain lengths, we observe that the rectification increases with the system size. We gain insight in the rectification mechanism by studying two-time correlations in the steady state. The presence of interactions also induces a strong nonlinear response to the temperature difference, resulting in superlinear and negative differential conductance regimes. arXiv:1809.01917v2 [cond-mat.stat-mech]FIG. 3: Interface tunneling. Rectification ratio versus anisotropy ∆ for different magnitudes of the tunneling at the interface between the interacting and the non-interacting halves of the chain (purple circles for J N/2 = 0.1, blue squares for J N/2 = 0.2, red triangles for J N/2 = 0.5 and green diamonds for J N/2 = 1.0). The smaller the interface tunneling J N/2 the stronger the rectification effect, however larger are the resonance effects due to finite size. Other parameters are N = 8, TC = 0.1 and TH = 10.

“…Later, the match/ mismatch mechanism is found to be effective to realize thermal rectification in anharmonic lattices with a mass gradient in the Fermi-Pasta-Ulam model 3 and a junction of two nonlinear lattices in the Frenkel-Kontorova model 4,5 . The Thermal rectification has been realized mainly based on heat conduction 1,[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] , besides phasechange material 23 , natural convection 1 , radiation 24 , evaporation and condensation 25 . Among these mechanisms, conduction-based thermal rectification shows great promise for phononics 26 and have been widely studied with nanoscale materials 6,11,15,[18][19][20][21][22] as well as bulk materials [8][9][10]12,16,17 via temperature-controlled locomotion 10 , mass loading 11 , heterogeneous junctions 6,8,9,12,[14]…”

In this work, we demonstrate two types of heterogeneous irradiated-pristine polyethylene nanofiber junctions, ‘heavily-irradiated-pristine’ (HI-P) and ‘lightly-irradiated-pristine’ (LI-P) junctions, as high-performance solid-state thermal diodes. The HI-P junction rectifies heat flux in a single direction, while the LI-P junction shows dual-directional rectification under different working temperatures. We accurately model the phase transition of polyethylene nanofibers with a finite temperature range rather than a step function. The finite-temperature-range model suggests that the rectification factor increases with temperature bias and there is a minimum threshold of temperature bias for notable rectification. Besides, the finite-temperature-range model shows better prediction for the heat flow data from experiments, while the step function model tends to overestimate the rectification performance around the optimal length fraction of irradiation. Although both the models show that an optimal rectification occurs when the interface temperatures in the forward and the reverse biases are equal, the optimized rectification factor is determined by the temperature bias and the temperature range of phase transition. This work elucidates the influence of both the temperature bias and the temperature range of phase transition on thermal rectification performance, which could incredibly benefit the evaluation and design of thermal diodes.

“…In these materials, it is important to take into account that not only phonons and electrons but also magnons transport heat. [ 145–147 ] A magnon is a quantized spin wave due to the exchange interaction of the electron spins in the ferromagnetic material. [ 148 ] It can be seen as a quasiparticle, whose properties are strongly dependent on the arrangement of the magnetic moments, the domain wall distribution, and the applied magnetic field.…”

Over the past decade, solid‐state thermal control devices have emerged as potential candidates for enhanced thermal management and storage. They distinguish themselves from traditional passive thermal management devices in that their thermal properties have sharp, nonlinear dependencies on direction and operating temperature, and can lead to more efficient circuits and energy conversion systems than what is possible today. They also distinguish themselves from traditional active thermal management devices (e.g., fans) in that they have no moving parts and are compact and reliable. In this article, the recent progress in the four broad categories of solid‐state thermal control devices that are under active research is reviewed: diodes, switches, regulators, and transistors. For each class of device, the operation principle, material choices, as well as metrics to compare and contrast performance are discussed. New architectures that are explored theoretically, but not experimentally demonstrated, are also discussed.
