Charge fluctuations and electron-phonon interaction in the finite- Hubbard model
E. Cappelluti, B. Cerruti, L. Pietronero
In this paper we employ a gaussian expansion within the finite- slave-bosons formalism to investigate the momentum structure of the electron-phonon vertex function in the Hubbar…
Electron-phonon renormalization in small Fermi energy systems
E. Cappelluti, L. Pietronero
The puzzling features of recent photoemission data in cuprates have been object of several analysis in order to identity the nature of the underlying electron-boson interaction. In…
Assortative model for social networks
Michele Catanzaro, Guido Caldarelli, Luciano Pietronero
In this paper we present a new version of a network growth model, generalized in order to describe the behavior of social networks. The case of study considered is the preprint arc…
Comment on ``Electron-phonon Vertex in the Two-dimensional One-band Hubbard Model''
B. Cerruti, E. Cappelluti, L. Pietronero
In cond-mat/0306131 Huang {\em et al.} reported for the first time a numerical evidence for the predominance of small phonon momenta in the electron-phonon coupling induced by elec…
