发展了密度矩阵重整化群方法的动量空间方法。用该方法计算了Hubbard模型的基态能量，并与精确对角化和量子蒙特卡罗结果进行了比较。它
A momentum-space approach of the density-matrix renormalization-group (DMRG) method is developed. Ground-state energies of the Hubbard model are evaluated using this method and compared with exact diagonalization as well as quantum Monte Carlo results. It
