Self-consistent inclusion of disorder in the BCS-BEC crossover near the critical temperature
M. Iskin
We develop a systematic theoretical approach to incorporate the effects of a static white-noise disorder into the BCS-BEC crossover near the critical temperature () of the sup…
Quenched disorder and the BCS-BEC crossover in the Hubbard model
M. Iskin
We study the impact of weak quenched disorder on the BCS-BEC crossover in the Hubbard model within a functional-integral approach. By deriving the thermodynamic potential up to sec…
Structure factors and quantum geometry in multiband BCS superconductors
M. Iskin
We consider multiband BCS superconductors that exhibit time-reversal symmetry and uniform pairing, and analyze their dynamic density and spin structure factors using linear-respons…
Pair size and quantum geometry in a multiband Hubbard model
M. Iskin
We study the size of two-body bound states and Cooper pairs within a multiband Hubbard model that features time-reversal symmetry and uniform pairing on a generic lattice. Our anal…
