A NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION
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

متن کاملElectron - phonon interaction in C 70
The matrix elements of the deformation potential of C 70 are calculated by means of a simple, yet accurate solution of the electron-phonon coupling problem in fullerenes, based on a parametrization of the ground state electronic density of the system in terms of sp 2+x hybridized orbitals. The value of the calculated dimensionless total electron-phonon coupling constant is λ ≈ 0.1, an order of ...
متن کاملElectron-phonon interaction and antiferromagnetic correlations.
We study effects of the Coulomb repulsion on the electron-phonon interaction (EPI) in the Holstein-Hubbard model, using the antiferromagnetic (AF) dynamical mean-field approximation. AF correlations strongly enhance EPI effects on the electron Green's function with respect to the paramagnetic correlated system, but the net effect of the Coulomb interaction is a moderate suppression of the EPI. ...
متن کاملElectronic structure and electron-phonon interaction in aluminium hydrides
2014 The superconducting transition temperature of high dose H implanted Al samples has been found by Lamoise et al., to be higher than that of pure Al. Since experimental observations indicate the possibility of H ordering, we have studied the changes in the electronic structure and the electron-phonon interaction of pure Al upon formation of A1H and A1H2. For this purpose, the McMillan parame...
