我们确定了非线性Maxwell-Cattaneo电荷输运理论在何种条件下允许具有特定修正动力学KMS对称性的局域高斯Schwinger-Keldysh嵌入。我们表明，将附加矢量视为本质上耗散的会从根本上修改熵流分析：静水生成泛函不再确定所有熵流改进，这些改进必须独立提供。随后，我们讨论了由修正KMS变换成为作用量对称性所施加的、不包含在流体动力学分析中的额外约束。我们既解释又提供了相应的随机准流体动力学。
英文摘要
We determine the conditions under which the nonlinear Maxwell-Cattaneo theory of charge transport admits a local Gaussian Schwinger-Keldysh embedding with a particular modified dynamical KMS symmetry. We show that treating the additional vector as intrinsically dissipative fundamentally modifies the entropy-current analysis: the hydrostatic generating functional no longer fixes all entropy-current improvements, which must instead be supplied independently. Subsequently we discuss the additional constraints not contained in the hydrodynamic analysis that are imposed by the modified KMS transformation becoming a symmetry of the action. We both interpret and supply the corresponding stochastic quasi-hydrodynamics.
