论文摘要
互环驱动的量子孔中粒子的动力学可以解释为晶体状结构中粒子的动力学，而时间扮演了坐标的作用。通过在驾驶方案中引入绝热相变的相位，我们证明了在这种时间晶体结构中无用的泵送的实现。接下来，我们通过考虑一个驱动的一维光学晶格，将分析扩展到单个量子井之外，从而设计了2D时空结构结构。这样的设置使我们能够分别探索空间和时间尺寸的绝热泵，并模拟同时的时间空间泵送。
Dynamics of particle in a resonantly driven quantum well can be interpreted as that of a particle in a crystal-like structure, with the time playing the role of the coordinate. By introducing an adiabatically varied phase in the driving protocol, we demonstrate a realization of the Thouless pumping in such a time crystalline structure. Next, we extend the analysis beyond a single quantum well by considering a driven one-dimensional optical lattice, thereby engineering a 2D time-space crystalline structure. Such a setup allows us to explore adiabatic pumping in the spatial and the temporal dimensions separately, as well as to simulate simultaneous time-space pumping.
