摘要：

The renormalization scheme recently proposed by White is applied to the Ising model in a transverse field. It is found that this scheme is a significant improvement over standard techniques as far as the computation of the ground state is concerned. It is shown that the errors in, the ground state energy are the largest in the neighborhood of the phase transition. Thus, this method has no special virtue in predicting the location of the phase transition and its associated critical exponents.
