Emergence of a Pseudogap in the BCS-BEC Crossover. [PDF]

open access: yesPhysical Review Letters, 2020
Strongly correlated Fermi systems with pairing interactions become superfluid below a critical temperature T_{c}. The extent to which such pairing correlations alter the behavior of the liquid at temperatures T>T_{c} is a subtle issue that remains an ...

The BCS-BEC Crossover [PDF]

open access: yes, 2014
This chapter presents the crossover from the Bardeen-Cooper-Schrieffer (BCS) state of weakly-correlated pairs of fermions to the Bose-Einstein condensation (BEC) of diatomic molecules in the atomic Fermi gas. Our aim is to provide a pedagogical review of

Non-equilibrium BCS-BEC crossover and unconventional FFLO superfluid in a strongly interacting driven-dissipative Fermi gas [PDF]

open access: yesAAPPS Bulletin
We present a theoretical review of the recent progress in non-equilibrium BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover physics.

Probing the BCS-BEC crossover with persistent currents [PDF]

open access: yesPhysical Review Research, 2021
We study the persistent currents of an attractive Fermi gas confined in a tightly confining ring trap and subjected to an artificial gauge field all through the BCS-BEC crossover. At weak attractions, on the Bardeen-Cooper-Schrieffer (BCS) side, fermions

Real-space BCS-BEC crossover in FeSe monolayers [PDF]

open access: yesPhysical Review B, 2022
The quantum many body states in the BCS-BEC crossover regime are of long-lasting interest. Here we report direct spectroscopic evidence of BCS-BEC crossover in real-space in a FeSe monolayer thin film by using spatially resolved scanning tunneling ...

Effect of Disorder in BCS-BEC Crossover [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2012
In this article we have investigated the effect of weak random disorder in the BCS-BEC crossover region. The disorder is included in the mean field formalism through NSR theory of superconducting fluctuations.

Relativistic BCS-BEC Crossover at Zero Temperature [PDF]

open access: yesPhysical Review D, 2007
We investigate the BCS-BEC crossover at zero temperature in the frame of a relativistic model. The universality of the BCS-BEC crossover for non-relativistic systems breaks down in relativistic case and the crossover can be induced by changing the ...

Solution Theory of Ginzburg-Landau Theory on BCS-BEC Crossover

open access: yesAdvances in Mathematical Physics, 2014
We establish strong solution theory of time-dependent Ginzburg-Landau (TDGL) systems on BCS-BEC crossover. By the properties of Besov, Sobolev spaces, and Fourier functions and the method of bootstrapping argument, we deduce that the global existence of ...

Thermodynamics of the BCS-BEC crossover [PDF]

open access: yesPhysical Review A, 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.
