Taariikhda qoraalka: | 2006 | Tifaftire: | Università degli Studi Roma Tre | Abstract: | In this work we present two variational approaches to the electron-phonon interaction in strongly correlated systems. The first approach that we discussed focuses mainly on the first aspect of the problem, whereas the second one completed the picture including a faithful description of phonon properties. We tested both in the paramagnetic sector of the Hubbard-Holstein model at T = 0, focusing on ground-state properties of both electrons and phonons. | URI : | http://hdl.handle.net/2307/68 |
