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…
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…
