沿弯曲界面的边缘态动力学
Edge state dynamics along curved interfaces
摘要：
我们研究波包沿着拓扑不同介质之间弱弯曲界面的传播。我们的哈密顿量是狄拉克算子的绝热调制无处不在的拓扑绝缘体文献。使用直边的显式公式，我们构建了一个家庭的解决方案，传播，很长一段时间，单向和分散免费沿弯曲的边缘。我们通过各种数值模拟来说明我们的结果。
英文摘要：
We study the propagation of wavepackets along weakly curved interfaces between topologically distinct media. Our Hamiltonian is an adiabatic modulation of Dirac operators omnipresent in the topological insulators literature. Using explicit formulas for straight edges, we construct a family of solutions that propagates, for long times, unidirectionally and dispersion-free along the curved edge. We illustrate our results through various numerical simulations.
