Quantum geometry of collective pairing fluctuations in the superfluid weight of multiband superconductors

R. N. Kalkan, M. Iskin

Beyond the frozen-pairing contribution, the superfluid weight of a multiband superconductor contains a correction from the self-consistent relaxation of the pairing amplitudes unde…

Coherence length and quantum geometry in a dilute flat-band superconductor

M. Iskin

To explore the influence of quantum-geometric effects on the Ginzburg-Landau coherence length in a dilute flat-band superconductor, we adopt a BCS-BEC crossover approach to the mul…

Cooper pairing, flat-band superconductivity and quantum geometry in the pyrochlore-Hubbard model

M. Iskin

We investigate the impacts of the quantum geometry of Bloch states, specifically through the band-resolved quantum-metric tensor, on Cooper pairing and flat-band superconductivity…

Extracting quantum-geometric effects from Ginzburg-Landau theory in a multiband Hubbard model

M. Iskin

We first apply functional-integral approach to a multiband Hubbard model near the critical pairing temperature, and derive a generic effective action that is quartic in the fluctua…

Rotation induced superfluid-normal phase separation in trapped Fermi gases

M. Iskin, E. Tiesinga

We use the Bogoliubov-de Gennes formalism to analyze the effects of rotation on the ground state phases of harmonically trapped Fermi gases, under the assumption that quantized vor…

Trapped fermion mixtures with unequal masses: a Bogoliubov-de Gennes approach

M. Iskin, C. J. Williams

We use the Bogoliubov-de Gennes formalism to analyze the ground state phases of harmonically trapped two-species fermion mixtures with unequal masses. In the weakly attracting limi…
