The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian}, keywords = {}, url = {https://jsciences.ut.ac.ir/article_31494.html}, eprint = {https://jsciences.ut.ac.ir/article_31494_8d28269f0740fee42b52a14e263e5f01.pdf} }
