针对存在增益损耗的三能级非厄米量子系统,提出了一种新型的非厄米受激拉曼绝热捷径(NH-STIRSAP)技术。该技术基于传统的受激拉曼......

不同于传统的厄米系统, 非厄米系统存在奇异点。当某一参数演化到奇异点时, 非厄米系统发生相变,即两个本征态合并成一个。利用耦......

Non-Hermitian quasicrystals possess PT and metal-insulator transitions induced by gain and loss or nonreciprocal effects......

We present an asymmetric absorber at an exceptional point (EP) with a compact configuration and deep-subwavelength thick......
