TY - JOUR ID - 31494 TI - A NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION JO - Journal of Sciences, Islamic Republic of Iran JA - JSCIENCES LA - en SN - 1016-1104 Y1 - 1999 PY - 1999 VL - 10 IS - 2 SP - EP - DO - N2 - A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. 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 UR - https://jsciences.ut.ac.ir/article_31494.html L1 - https://jsciences.ut.ac.ir/article_31494_8d28269f0740fee42b52a14e263e5f01.pdf ER -
