将密度矩阵重整化群理论作为一种数值变分方法进行了综述。用局部张量的乘积表示的变分状态通过局部调整每个张量来改善。第一部分是简化讨论的教程。详细信息将在后续各节中讨论。综述最后提出了一些最新进展和未来方向。
The density matrix renormalization group theory is reviewed as a numerical variational method. The variational state, expressed as a product of local tensors, is improved through locally tuning each tensor. The first section is a tutorial with simplified discussions. Details are discussed in the subsequent sections. The review concludes with some recent developments and future directions.
