我们提出了一种针对一维量子晶格模型和二维经典模型的快速数值重整化群方法——乘积波函数重整化群（PWFRG）方法。通过自洽计算改进了表示为矩阵乘积的变分波函数。新方法与密度矩阵重整化群方法具有相同的不动点。
We propose a fast numerical renormalization group method-the product wave function renormalization group (PWFRG) method-for 1D quantum lattice models and 2D classical ones. A variational wave function, which is expressed as a matrix product, is improved through a self-consistent calculation. The new method has the same fixed point as the density matrix renormalization group method.
