Multiple Gaps and Superfluid Density from Interband Pairing in Iron Oxypnictides
L. Benfatto, M. Capone, S. Caprara +2
We study a four-band model for the iron oxypnictides, in which the superconducting properties are assumed to be determined by the interband coupling between hole-like and electron-…
Gutzwiller scheme for electrons and phonons: the half-filled Hubbard-Holstein model
P. Barone, R. Raimondi, M. Capone +2
We analyze the ground-state properties of strongly-correlated electrons coupled with phonons by means of a generalized Gutzwiller wavefunction which includes phononic degrees of fr…
Strongly Correlated Superconductivity rising from a Pseudo-gap Metal
Marco Schiro', Massimo Capone, Michele Fabrizio +1
We solve by Dynamical Mean Field Theory a toy-model which has a phase diagram strikingly similar to that of high superconductors: a bell-shaped superconducting region adjacen…
Doping dependence of the vortex-core energy in bilayer films of cuprates
L. Benfatto, C. Castellani, T. Giamarchi
The energy needed to create a vortex core is the basic ingredient to address the physics of thermal vortex fluctuations in underdoped cuprates. Here we theoretically investigate it…
