Variational study of the extended Hubbard-Holstein model on clusters of variable site spacing
Marcello Acquarone, Mario Cuoco, Canio Noce +1
We study the complete extended Hubbard-Holstein Hamiltonian on a four-site chain with equally spaced sites, with spacing-dependent electronic interaction parameters evaluated in te…
A non-perturbative treatment of the generalized Su-Schreiffer-Heeger Hamiltonian on a dimer
M. Cococcioni, M. Acquarone
Starting from the Hamiltonian for a dimer which includes all the electronic and electron-phonon terms consistent with a non-degenerate orbital, by a sequence of displacement and sq…
Distance-depending electron-phonon interactions from one- and two-body electronic terms in a dimer
M. Acquarone, C. Noce
For a dimer with a non-degenerate orbital built from atomic wave functions of Gaussian shape we evaluate all the electron-phonon couplings derived from the one-body and two-body el…
