- 論文の詳細を見る
New variational wave functions are introduced tc>describe the Llubbard model instrong correlatuon. Intersite correlation (or Jastrow') factors are taken into accountbeyond the Gutzwiller wave function (GF). A study is made o?a the one-dimensionallattice and the two-dimensional square lattice at half-filling as ',veil as less-than-halffilling. Much improvement can be achieved thereby in the dc;scription of physicalquantities such as the momentum distribution and spin and charge density correlationfunctions. In addition, the ground state energy is No',vered appreciably compared withthe GF. In this connection, the Molt-Hubbard-type metal-insulator transition is alsore-examined.
