摘要：

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.
