Fermi-Bose Mixtures and BCS-BEC Crossover in High-Tc Superconductors [PDF]
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 ...

Advances in Condensed Matter Physics, 2015 Recent experimental progress allows for exploring some important physical quantities of ultracold Fermi gases, such as the compressibility, spin susceptibility, viscosity, optical conductivity, and spin diffusivity. Theoretically, these quantities can be

Precise Photoexcitation Measurement of Tan's Contact in the Entire BCS-BEC Crossover. [PDF]
Physical Review Letters, 2023 We study two-body correlations in a spin-balanced ultracold harmonically trapped Fermi gas of ^{6}Li atoms in the crossover from the Bardeen-Cooper-Schrieffer (BCS) to the Bose-Einstein-Condensate (BEC) regime.

Gate-controlled BCS-BEC crossover in a two-dimensional superconductor [PDF]
Science, 2020 Inducing a crossover In conventional superconductors, the electron pairs responsible for superconductivity are large and overlapping. Starting from this so-called Bardeen-Cooper-Schrieffer (BCS) limit, increasing interactions can set the system on a path

Following the Higgs mode across the BCS-BEC crossover in two dimensions [PDF]
Physical review B, 2023 Although substantial effort has been dedicated to analyzing the Higgs (amplitude) mode in superconducting systems, there are relatively few studies of the Higgs peak's dispersion and width, quantities which are observable in spectroscopic measurements ...

Communications Physics, 2023 The BCS-BEC (Bardeen-Cooper-Schrieffer–Bose-Einstein-condensate) crossover from strongly overlapping Cooper pairs to non-overlapping composite bosons in the strong coupling limit has been a long-standing issue of interacting many-body fermion systems ...

Attractors of Modified Coupled Ginzburg–Landau Model
Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023 Bose–Einstein condensation is a gaseous, superfluid state of matter exhibited by bosons as they cool to near absolute zero, which was discovered as early as 1924 but was not experimentally realized until 1995. In 2006, Machida and Koyama developed the corresponding Ginzburg–Landau model for superfluid and Bose–Einstein condensation‐spanning phenomena ...

Mott-Driven BEC-BCS Crossover in a Doped Spin Liquid Candidate κ-(BEDT-TTF)_{4}Hg_{2.89}Br_{8}
Physical Review X, 2022 The pairing of interacting fermions leading to superfluidity has two limiting regimes: the Bardeen-Cooper-Schrieffer (BCS) scheme for weakly interacting degenerate fermions and the Bose-Einstein condensation (BEC) of bosonic pairs of strongly interacting
