论文摘要
对于以自发的断裂对称稳态制备的驱动驱动量子多体系统，除了金石模式外，软波动模式还为系统的动态提供了重要的见解。使用显微镜极化激光理论，我们在两个参数（泵密度和空腔耗散速率）空间中发现了离散和连续软模式的丰富变换行为。除了找到出色的戈德石伴侣模式外，我们的理论还产生了各种看似脱节的物理概念的统一图片，包括Mott Transition，Mollow Spectra或Halise振荡以及Polaritonic Bardeen-Cooper-Schrieffer Gaps。
For a driven-dissipative quantum many-body system prepared in a spontaneous broken-symmetry steady state, in addition to the Goldstone mode the soft fluctuation modes provide important insight into the system's dynamics. Using a microscopic polariton laser theory, we find a rich transformation behavior of discrete and continuum soft modes in a two parameter (pump density and cavity dissipation rate) space. In addition to finding exceptional-point Goldstone companion modes, our theory yields a unified picture of a variety of seemingly disconnected physical concepts including Mott transition, Mollow spectra or relaxation oscillations, and polaritonic Bardeen-Cooper-Schrieffer gaps.
