Electron-phonon Interaction close to a Mott transition
G. Sangiovanni, M. Capone, C. Castellani +1
The effect of Holstein electron-phonon interaction on a Hubbard model close to a Mott-Hubbard transition at half-filling is investigated by means of Dynamical Mean-Field Theory. We…
Interplay between density and superconducting quantum critical fluctuations
S. Caprara, N. Bergeal, J. Lesueur +1
We consider the case of a density-driven metal-superconductor transition in the proximity of an electronic phase separation. In particular we investigate the interplay between supe…
Re-entrant charge order in overdoped (Bi,Pb)SrCuO outside the pseudogap regime
Y. Y. Peng, R. Fumagalli, Y. Ding +15
Charge modulations are considered as a leading competitor of high-temperature superconductivity in the underdoped cuprates, and their relationship to Fermi surface reconstructions…
Casimir energy for two and three superconducting coupled cavities
L. Rosa, S. Avino, E. Calloni +16
In this paper we study the behavior of the Casimir energy of a "multi-cavity" across the transition from the metallic to the superconducting phase of the constituting plates. Our a…
Influence of electron-phonon interaction on superexchange
W. Stephan, M. Capone, M. Grilli +1
We investigate the influence of electron-phonon coupling on the superexchange interaction of magnetic insulators. Both the Holstein-Hubbard model where the phonons couple to the el…
Comment on ``Insulator-to-Metal Crossover in the Normal State of Near Optimum Doping''
C. Castellani, C. Di Castro, M. Grilli
We underline and comment some features of the data obtained in the beautiful experiment by G. S. Boebinger, Y. Ando, A. Passner, T. Kimura, M. Okuya, J. Shimoyama, K. Kishio, K. Ta…
