Two-bands superconductivity with intra- and interband pairing for synthetic superlattices

Alex A. Schmidt, Jose J. Rodríguez-Núñez, Antonio Bianconi +1

We consider a model for superconductivity in a two-band superconductor, having an anisotropic electronic structure made of two partially overlapping bands with a first hole-like an…

Shape resonance at a Lifshitz transition for high temperature superconductivity in multiband superconductors

Davide Innocenti, Antonio Valletta, Antonio Bianconi

We discuss the shape resonance in the superconducting gaps of a two band superconductor by tuning the chemical potential at a Lifshitz transition for Femi surface neck collapsing a…

Shape resonance for the anisotropic superconducting gaps near a Lifshitz transition: the effect of electron hopping between layers

Davide Innocenti, Sergio Caprara, Nicola Poccia +3

The multigap superconductivity modulated by quantum confinement effects in a superlattice of quantum wells is presented. Our theoretical BCS approach captures the low-energy physic…

Scale-free structural organization of oxygen interstitials in La2CuO4+y

Michela Fratini, Nicola Poccia, Alessandro Ricci +4

It is well known that the microstructures of the transition-metal oxides (refs 1-3), including the high-transition-temperature (high-Tc) copper oxide superconductors (refs 4-7), ar…

Structural phase transition and superlattice misfit strain of RFeAsO (R = La, Pr, Nd and Sm)

Alessandro Ricci, Nicola Poccia, B. Joseph +9

The tetragonal-to-orthorhombic structural phase transition (SPT) in LaFeAsO (La-1111) and SmFeAsO (Sm-1111) single crystals measured by high resolution x-ray diffraction is found t…

Resonant and crossover phenomena in a multiband superconductor tuning the chemical potential near a band edge

Davide Innocenti, Nicola Poccia, Alessandro Ricci +4

Resonances in the superconducting properties, in a regime of crossover from BCS to mixed Bose-Fermi superconductivity, are investigated in a two-band superconductor where the chemi…
