• Authors: Israel D\'iaz and Rafael S\'anchez
• Abstract summary: We investigate the heat transport properties of a three-level system coupled to three thermal baths, assuming a model based on superconducting circuit implementations. We find thermal rectification and circulation effects not expected in configurations with perfectly-filtered couplings. Heat leakage in off-resonant transitions can be exploited to make the system work as an ideal diode where heat flows in the same direction between two baths irrespective of the sign of the temperature difference.

• Abstract: We investigate the heat transport properties of a three-level system coupled to three thermal baths, assuming a model based on superconducting circuit implementations. The system-bath coupling is mediated by resonators which serve as frequency filters for the different qutrit transitions. Taking into account the finite quality factors of the resonators, we find thermal rectification and circulation effects not expected in configurations with perfectly-filtered couplings. Heat leakage in off-resonant transitions can be exploited to make the system work as an ideal diode where heat flows in the same direction between two baths irrespective of the sign of the temperature difference, as well as a perfect heat circulator whose state is phase-reversible.

  A quantum thermal device based on three nearest-neighbor coupled spin-1/2 systems controlled by the magnetic field is proposed. We systematically study the steady-state thermal behaviors of the system. We find that the transverse field can induce the system to separate into two subspaces in which neither steady-state heat current vanishes.

  We explore a prototype of an oscillatory neural network (ONN) based on vanadium dioxide switching devices.

In the case of a strong thermal coupling, the limit of the supply current parameters, for which the oscillations exist, expands by 10 %. The effect of subharmonic synchronization hold promise for application in classification and pattern recognition.
