Single-electron heat diode: Asymmetric heat transport between electronic reservoirs through Coulomb islands

Qubit-mediated energy transfer between thermal reservoirs: Beyond the Markovian master equation

“…This choice corresponds to 0 < ν F < 0.08 when = 0.1, see Eq. (25). For this set of model parameters, we have confirmed that selecting δt = 0.8-1.5 and N s = 6-9 (yielding memory time τ c 8) provides converging results, see Figs.…”

“…20,21 Particularly, it has been recently adopted for modeling radiative the energy transfer between metals, 13,28 and for studying charge and energy transfer phenomenology in mesoscopic systems 19,22,24,25 and single molecules. 23,38 It is thus important to test the suitability and accuracy of this common and well-accepted approximate scheme against exact results.…”

Heat diode and engine based on quantum Hall edge states

“…When the ratio of the two currents is large enough, the system behaves as a heat diode, a key element for the control of heat in electronic devices [33]. This effect has been shown to be prominent in mesoscopic conductors [34][35][36][37][38][39]. We show that the physics of the quantum Hall effect can be used to construct a perfect heat diode in the linear regime.…”

Thermal rectification of electrons in hybrid normal metal-superconductor nanojunctions

“…In this regard, a NS junction therefore behaves as a thermal diode 18,19 with this meaning that heat conduction along one direction is preferred with respect to that occurring upon temperature bias reversal. Strong effort has been devoted so far to envision and to realize thermal rectifiers dealing, for instance, either with phonons, 20-24 electrons, 17,[25][26][27][28][29] or with photons. 30 In this letter, we address the heat diode effect in NS nanojunctions and explore how thermal rectification depends on the interface properties.…”
