论文摘要
我们提出了一个设置,以创建和检测蛇状态轨迹的原子对应物,该蛇状态轨迹发生在磁场逆转方向的界面处。通过将环腔的两个反向传输模式耦合到两级原子来产生这样的磁场。诱导磁场的空间分布和强度分别由腔模式的横向模式曲线和两个模式中的光子数量控制。通过在包括腔体背动物在内的同时分析这种磁场中的原子运动,我们发现原子遵循蛇状态轨迹,这些轨迹可以从相相,从腔中泄漏的光场的强度和强度从腔体泄漏。我们最终表明,可以调整系统参数以修改蛇状态的传输特性,甚至可以放大腔反馈的效果,这可以完全改变其拓扑。
We propose a set-up to create and detect the atomic counterpart of snake state trajectories which occur at the interface where the magnetic field reverses direction. Such a magnetic field is generated by coupling two counter-propagating modes of a ring cavity to a two-level atom. The spatial distribution and the strength of the induced magnetic field are controlled by the transverse mode profile of the cavity modes and the number of photons in the two modes, respectively. By analysing the atomic motion in such a magnetic field while including the cavity back-action, we find that the atom follows snake state trajectories which can be non-destructively detected and reconstructed from the phase and the intensity of the light field leaking from the cavity. We finally show that the system parameters can be tuned to modify the transport properties of the snake states and even amplify the effect of cavity feedback which can completely alter their topology.
