论文摘要
我们证明了吉布斯的变化公式在量子相对熵密度方面,表征了量子晶格系统中翻译不变的热平衡状态。这是Föllmer为古典系统建立的类似陈述的自然量子扩展。在这项工作中,我们提倡观点:如果不是必需的,则避免唯一的假设。
We prove the Gibbs variational formula in terms of quantum relative entropy density that characterizes translation invariant thermal equilibrium states in quantum lattice systems. It is a natural quantum extension of the similar statement established by Föllmer for classical systems. In this work we advocate the viewpoint: Avoid the unique-phase assumption if it is not essential.
