论文摘要
我们研究了量子穿着的主方程框架中耗散性各向异性量子兔模型中的量子相变。从数值和分析分析的角度来看，我们揭示了巨型光子束特征对一阶量子相变的含义。在低温下，观察到的两光子统计量可以在几个最低的本征态内进行分析。此外，这种显着的光子束峰通常在深度Qubit-Photon耦合处表现出来，然而，在耗散性各向同性量子兔模型中缺乏。因此，我们建议光子束式测量有助于表征Qubit-Photon混合系统的一阶QPT。
We investigate the quantum phase transition in the dissipative anisotropic quantum Rabi model in the framework of quantum dressed master equation. From perspectives of both numerical and analytical analysis, we unravel the implication of the giant photon-bunching feature on the first-order quantum phase transition. The observed two-photon statistics can be well described analytically within a few lowest eigenstates at the low temperature. Moreover, such significant photon-bunching peak is generally exhibited at the deep-strong qubit-photon coupling, which is however lacking in the dissipative isotropic quantum Rabi model. Therefore, we suggest that the photon-bunching measurement is helpful to characterize the first-order QPT of the qubit-photon hybrid systems.
