论文摘要
在本手稿中，我们报告了准二元刚度调制光束中的绝热泵送。我们表明，填充非平凡间隙的不同拓扑状态可以构成以边缘到边缘过渡为特征的避免的横梁。当调制阶段的平滑变化沿着合成维度诱导时，这种状态固有地耦合，从而导致拓扑边缘到边缘转运来自穿越状态的明显极化。我们首先提出一个通用框架，以估算给定过渡概率的所需调制速度。然后，利用此分析工具在刚度调制的光束中量身定制拓扑泵送。
In this manuscript we report on adiabatic pumping in quasiperiodic stiffness modulated beams. We show that distinct topological states populating nontrivial gaps can nucleate avoided crossings characterized by edge-to-edge transitions. Such states are inherently coupled when a smooth variation of the modulation phase is induced along a synthetic dimension, resulting in topological edge-to-edge transport stemming from distinct polarizations of the crossing states. We first present a general framework to estimate the required modulation speed for a given transition probability in time. Then, this analysis tool is exploited to tailor topological pumping in a stiffness modulated beam.
