论文摘要
我们提出了一项具体的理论建议，用于检测双踢原子镜的拓扑相变，并具有内部自旋1/2的自由度。该实施利用了在一维动量空间中演变的踢玻色网凝结物。为了降低原子损失和相位逆转的影响，我们旨在保持实验持续时间短，同时保持共振的实验方案。考虑了相位噪声，准分布，对称性和AC-Stark Shings引起的实验局限性。因此，我们的结果提出了一个可行且优化的程序，用于观察量子踢转子中的拓扑相变。
We present a concrete theoretical proposal for detecting topological phase transitions in double kicked atom-optics kicked rotors with internal spin-1/2 degree of freedom. The implementation utilizes a kicked Bose-Einstein condensate evolving in one-dimensional momentum space. To reduce influence of atom loss and phase decoherence we aim to keep experimental durations short while maintaining a resonant experimental protocol. Experimental limitations induced by phase noise, quasimomentum distributions, symmetries, and the AC-Stark shift are considered. Our results thus suggest a feasible and optimized procedure for observing topological phase transitions in quantum kicked rotors.
