- 研究由一个金属纳米线中的表面等离子激元与两个量子点耦合构成的非厄米量子系统中表面等离子激元的单向无反射传输现象,通过适当地调整两个量子点之间的相位差,在异常点实现了表面等离子激元的单向无反射.
- Abstract:
- We investigate the unidirectional reflectionless propagation of surface plasmon in non-Hermitian quantum system. The non-Hermitian quantum system consists of a surface plasmon coupling to two quantum dots in a metal nanowire. By appropriately tuning the phase difference between two quantum dots, we demonstrate the unidirectional reflectionless propagation of surface plasmon at exceptional point.
