论文摘要
我们研究沿拓扑，磁性材料之间弯曲界面的波袋的传播。我们的哈密顿量是具有磁性电势的巨大狄拉克操作员。我们构建了沿弯曲界面传播的半古老波袋，作为在恒定磁场下的直边状态的绝热调制。在无磁性的情况下，波袋以速度一致地传播，在这里，它们经历了放缓，分散和aharonov -bohm效应。几个数值模拟说明了我们的结果。
We study the propagation of wavepackets along curved interfaces between topological, magnetic materials. Our Hamiltonian is a massive Dirac operator with a magnetic potential. We construct semiclassical wavepackets propagating along the curved interface as adiabatic modulations of straight edge states under constant magnetic fields. While in the magnetic-free case, the wavepackets propagate coherently at speed one, here they experience slowdown, dispersion, and Aharonov - Bohm effects. Several numerical simulations illustrate our results.
