论文摘要
我们执行理论计算，以在双量子点DQD中研究稳态电子传输，并在谐振和强度耦合方面耦合到谐振和异位方向上的量化腔光子光场。在谐振强耦合方面，发现DQD和腔之间的光子交换反映了多种rabi-son的共和力。通过调整腔体环境耦合强度，可以平稳地增加状态的电子占用和传输电流。使系统偏离谐波，但仍处于强耦合状态，光子交换减少了，并且系统的电子占用及通过它的传输电流对于高空腔 - 环境偶联强度而言是突出的。在DQD和腔之间的弱耦合方案中，该系统在谐振剂和空腔环境耦合强度高值下的谐振和异化状态几乎具有相同的响应。
We perform theoretical calculations to study steady-state electron transport in a double quantum dot, DQD, coupled to a quantized cavity photon field both in resonance and off-resonance regimes considering weak and strong coupling. In the resonant strong coupling regime, photon exchanges between the energy states of the DQD and the cavity are found reflecting multiple Rabi-resonances. The electron occupation of the states and the transport current can be smoothly increased by tuning the cavity-environment coupling strength. Making the system off-resonant, but still in the strong coupling regime, the photon exchange is diminished and the electron occupation of the system and the transport current through it are prominent for high cavity-environment coupling strength. In the weak coupling regime between the DQD and the cavity, the system has almost the same response in the resonant and the off-resonant regimes at high values of the cavity-environment coupling strength.
