论文摘要
在这项工作中，我们探讨了与连续相变处耗散系统的稳态相关的忠诚度敏感性和痕量距离敏感性的关键行为。我们研究了两个典型模型，一个是二维方晶格上的耗散性旋转1/2 XYZ模型，另一个是驱动的Kerr振荡器。我们发现，在这两个模型中，相位转变的临界点附近的忠诚度和痕量距离呼出的奇异行为的敏感性。从热力学极限中，从关键控制参数的量表提取到系统大小或非线性的临界点与存在的结果非常吻合。
In this work, we explore the critical behaviors of fidelity susceptibility and trace distance susceptibility associated to the steady states of dissipative systems at continuous phase transitions. We investigate on two typical models, one is the dissipative spin-1/2 XYZ model on two-dimensional square lattice and the other is a driven-dissipative Kerr oscillator. We find that the susceptibilities of fidelity and trace distance exhabit singular behaviors near the critical points of phase transitions in both models. The critical points, in thermodynamic limit, extracted from the scalings of the critical controlling parameters to the system size or nonlinearity agree well with the existed results.
