- Abstract: Controlling heat flow at the quantum level is essential for the development of next-generation thermal devices. We investigate thermal rectification in a quantum harmonic oscillator coupled to two thermal baths via both single-photon (linear) and two-photon (nonlinear) exchange processes. At low temperatures, rectification arises from a state-dependent suppression of two-photon emission: when the cold bath dominates, it drives the oscillator into low-occupancy states, inhibiting emission and creating a thermal bottleneck. At higher temperatures, rectification is governed by the asymmetric scaling of higher-order moments associated with two-photon absorption and emission. We systematically explore various bath coupling configurations and identify the conditions under which nonlinear dissipation leads to directional heat flow. Furthermore, we propose an implementation scheme based on coupling an auxiliary two-level system to the oscillator, enabling effective two-photon dissipation. These results contribute to the understanding of quantum heat transport in the presence of nonlinear dissipation and may support future efforts in nanoscale thermal rectification design.

We build a two-bath model where the qubit couples simultaneously to a cold bath (the waveguide) and a hot bath (a secondary environment)
Results show that the thermal-photon occupation of the hot bath is up to 0.14 photons, 35 times larger than the cold waveguide.
Our interpretation is that the hot bath may arise from active two-level systems being excited by noise from the output line.
