论文摘要
我们证明了刚建立的浮雕驱动耗散dicke模型的最近建立的Floquet辅助超级阶段的鲁棒性，灵感来自石墨烯中的光诱导动力学。特别是，我们表明了这种状态对关键缺陷的鲁棒性，并主张将其用于激光操作的可行性。我们考虑通过相扩散建模的有限线宽的效果。我们发现，空腔中的光场的线宽在FSP过渡时大大缩小，让人联想到激光过渡时线变窄。然后，我们证明了FSP对不均匀宽的宽敞，同时显示出光强度的降低。我们表明，近谐振的浮子状态的人口反转导致无约瑟式宽阔的浮子光谱燃烧。最后，我们表明FSP在耗散过程中具有鲁棒性，其系数达到了实验可用的值。我们得出的结论是，FSP提出了一种能够逼真的激光操作的强大机制。
We demonstrate the robustness of the recently established Floquet-assisted superradiant phase of the parametrically driven dissipative Dicke model, inspired by light-induced dynamics in graphene. In particular, we show the robustness of this state against key imperfections and argue for the feasibility of utilizing it for laser operation. We consider the effect of a finite linewidth of the driving field, modelled via phase diffusion. We find that the linewidth of the light field in the cavity narrows drastically across the FSP transition, reminiscent of a line narrowing at the laser transition. We then demonstrate that the FSP is robust against inhomogeneous broadening, while displaying a reduction of light intensity. We show that the depleted population inversion of near-resonant Floquet states leads to hole burning in the inhomogeneously broadened Floquet spectra. Finally, we show that the FSP is robust against dissipation processes, with coefficients up to values that are experimentally available. We conclude that the FSP presents a robust mechanism that is capable of realistic laser operation.
