我们证明了最近导出的远离平衡的量子系统的守恒电荷与其相关的守恒电流之间的关联相等[O.A.Castro-Alvaredo，B.Doyon和T.Yoshimura，Phys.X6,041065(2016年)]，在比迄今假定的更一般的条件下有效。类似的关联恒等式，在广义Gibbs系综中产生了某种程度上让人想起Onsager关系的电流对称性，在没有平移不变性的情况下，对于晶格模型和在任何空间维度中也是成立的，并且意味着非平衡线性响应函数的对称性。
We prove that a recently derived correlation equality between conserved charges and their associated conserved currents for quantum systems far from equilibrium [O.A. Castro-Alvaredo, B. Doyon, and T. Yoshimura, Phys. Rev. X 6, 041065 (2016)], is valid under more general conditions than assumed so far. Similar correlation identities, which in generalized Gibbs ensembles give rise to a current symmetry somewhat reminiscent of the Onsager relations, turn out to hold also in the absence of translation invariance, for lattice models, and in any space dimension, and to imply a symmetry of the non-equilibrium linear response functions.
