Test for BCS-BEC crossover in the cuprate superconductors
npj Quantum MaterialsIn this paper we address the question of whether high-temperature superconductors have anything in common with BCS-BEC crossover theory. Towards this goal, we present a proposal and related predictions which provide a concrete test for the applicability ...

Thermodynamics of the BCS-BEC crossover
, 2007 We present a self-consistent theory for the thermodynamics of the BCS-BEC crossover in the normal and superfluid phase which is both conserving and gapless.

Collective oscillation modes of a superfluid Bose–Fermi mixture
New Journal of Physics, 2019 In this work, we present a theoretical study for the collective oscillation modes, i.e. quadrupole, radial and axial mode, of a mixture of Bose and Fermi superfluids in the crossover from a Bardeen-Cooper-Schrieffer (BCS) superfluid to a molecular Bose ...

BCS BEC crossover and phase structure of relativistic system: a variational approach
, 2009 We investigate here the BCS BEC crossover in relativistic systems using a variational construct for the ground state and the minimization of the thermodynamic potential.

Superfluid stability in BEC-BCS crossover
, 2005 We consider a dilute atomic gas of two species of fermions with unequal concentrations under a Feshbach resonance. We find that the system can have distinct properties due to the unbound fermions. The uniform state is stable only when either (a) beyond a

Leggett collective excitations in a two-band Fermi superfluid at finite temperatures
New Journal of Physics, 2019 The Leggett collective excitations for a two-band Fermi gas with s -wave pairing and Josephson interband coupling in the BCS-BEC crossover at finite temperatures are investigated within the Gaussian pair fluctuation approach. Eigenfrequencies and damping

Fermi-Bose Mixtures and BCS-BEC Crossover in High-Tc Superconductors
Condensed Matter, 2019 In this review article we consider theoretically and give experimental support to the models of the Fermi-Bose mixtures and the BCS-BEC (Bardeen Cooper Schrieffer−Bose Einstein) crossover compared with the strong-coupling approach, which can serve ...

BCS-BEC crossover and superconductor-insulator transition in Hopf-linked Graphene layers: Hopfene
Materials Research Express, 2019 We have proposed a topological carbon allotrope, named Hopfene, which has three-dimensional (3 D ) arrays of Hopf-links to bind 2 D Graphene layers both horizontally and vertically without forming strong σ bonds between layers. Tight-binding calculations
