概要

• 論文の詳細を見る

• An approximate variational method of calculating the ground state energy ofthe Hubbard model is presented. The method is based on the trial wave functionof Wigner. The result for the one-dimensional model is good compared withother approximate results. The extension of the method to finute temperatures usstraightforward.
