论文摘要
我们通过施加嵌入具有声音连贯状态的量子主方程来研究非平衡Qubit-Phonon混合系统中的量子传热和热管理。我们通过调整任意量子轴耦合强度来获得稳态热流，该耦合强度分别表现出幂律缩放行为和弱和强耦合方案中的周转行为。此外，我们分析了负差分电导和热整流，这在弱量子 - phonon相互作用和较大温度偏置的情况下变得深刻。这些结果将有助于智能能源控制和语音混合量子设备的设计。
We investigate quantum heat transfer and thermal management in the nonequilibrium qubit-phonon hybrid system by applying the quantum master equation embedded with phononic coherent state. We obtain the steady state heat flow by tuning the arbitrary qubit-phonon coupling strength, which particularly exhibits the power-law scaling behavior and the turnover behavior in the weak and strong coupling regimes, respectively. Moreover, we analyze the negative differential thermal conductance and thermal rectification, which becomes profound with weak qubit-phonon interaction and large temperature bias. These results would contribute to smart energy control and design of phononic hybrid quantum devices.
