论文摘要
我们研究了由非谐波泵激发的激子 - 果态凝结物的多稳定性。泵浦功率的增加使系统从非热光谱退化转向通过特殊点裂解的光谱分裂,从而导致从单位稳定性转变为多稳定性。在多稳定性区域中,该系统包含一个稳定和两个亚稳态状态。稳定性的分析表明,亚稳态状态保持有限的寿命,并最终发展为稳态。发现具有吸引力的Polariton-Polariton相互作用的具有多峰甲龙的稳态不同。此外,我们描述了完整参数空间中的多稳定性图,以准确操纵多稳定性。我们的结果为控制非量子量子多稳态状态开辟了令人兴奋的可能性,这对于设计利用光学多稳定性的基于极化的设备可能很有用。
We investigate the multistability of exciton-polariton condensates excited by a nonresonant pump. An increase in pumping power moves the system away from non-Hermitian spectral degeneracy towards spectrum splitting through an exceptional point, which induces a transition from monostability to multistability. In the region of multistability, the system contains one steady and two metastable states. The analyses of stability show that metastable states maintain a finite lifetime and eventually evolve to steady states. A steady state with multi-peak soliton different from general single-peak soliton is discovered for attractive polariton-polariton interaction. Moreover, we depict the diagram of the multistability in full parameter space to accurately manipulate the multistability. Our results open up exciting possibilities for controlling non-Hermitian quantum multistable states, which may be useful to designing polariton-based devices exploiting optical multistability.
