Lifshitz Transitions in 122-Pnictides Under Pressure
Khandker Quader, Michael Widom
We demonstrate, using first principles total energy calculations, that observed pressure-driven anomalies in the entire 122-pnictides family (FeAs; = alkali ea…
Signatures of Fermion Pairing with Unconventional Symmetry around BCS-BEC Crossover in a Quasi-2D Lattice
Dušan Volčko, Khandker F. Quader
We consider fermions on a 2D square lattice with a finite-range pairing interaction, and obtain signatures for unconventional pair-symmetry states, and extended-s ($s…
p-wave Pairing in Two-Component Fermi System with Unequal Population: Weak Coupling BCS to Strong Coupling BEC Regimes
Renyuan Liao, Florentin Popescu, Khandker Quader
We study p-wave pairing in a two-component Fermi system with unequal population across weak-coupling BCS to strong-coupling BEC regimes. We find a rich spin triplet p-wave…
P-wave Pairing in Two-Component Fermi Systems with Unequal Population near Feshbach Resonance
R. Liao, F. Popescu, K. Quader
We explore p-wave pairing in a single-channel two-component Fermi system with unequal population near Feshbach resonance. Our analytical and numerical study reveal a rich superflui…
Pairing with Unconventional Symmetry around BCS-BEC Crossover: Fermionic Atoms in 2D Optical Lattices to Correlated Electron Systems
Dusan Volcko, Khandker F. Quader
We study superfluid properties of fermions on a 2D lattice using a finite-range pairing interaction derivable from an extended Hubbard model. We obtain signatures of unconventional…
Pairing in Asymmetrical Fermi Systems with Intra- and Inter-Species Correlations
Renyuan Liao, Khandker F. Quader
We consider inter- and intra-species pairing interactions in an asymmetrical Fermi system. Using equation of motion method, we obtain coupled mean-field equations for superfluid ga…
