We propose a second renormalization group method to handle the tensor-network states or models. This method dramatically reduces the truncation error of the tensor renormalization group. It allows physical quantities of classical tensor-network models or tensor-network ground states of quantum systems to be accurately and efficiently determined.
我们提出了第二种重整化群方法来处理张量网络态或模型。这种方法显著降低了张量重整化群的截断误差。它使得经典张量网络模型或量子系统的张量网络基态的物理量能够被精确和有效地确定。
