连续介质中的准束缚态
Quasi-bound states in continuum
摘要：
我们报告的预测准束缚态（共振态具有很长的寿命），发生在传播状态的本征值连续的参数空间的一个很宽的区域。当两个通道的能带重叠时，在具有两个通道和一个吸附原子的量子线中产生这些准束缚态。位于上能带正下方的可能的束缚态被下能带稍微破坏，从而成为具有非常长寿命的共振态（第二个QBIC位于下能带上方）。
英文摘要：
We report the prediction of quasi-bound states (resonant states with very long lifetimes) that occur in the eigenvalue continuum of propagating states for a wide region of parameter space. These quasi-bound states are generated in a quantum wire with two channels and an adatom, when the energy bands of the two channels overlap. A would-be bound state that lays just below the upper energy band is slightly destabilized by the lower energy band and thereby becomes a resonant state with a very long lifetime (a second QBIC lays above the lower energy band).
