BCS to Bose crossover: Broken-symmetry state
Abstract
A functional integral formulation, used previously to calculate ${\mathrm{T}}_{\mathrm{c}}$ and describe normal state properties of the BCS-Bose crossover, is extended to T${\mathrm{T}}_{\mathrm{c}}$. The saddle point approximation is shown to be qualitatively correct for T\ensuremath{\ll}${\mathrm{T}}_{\mathrm{c}}$ for all couplings, in contrast to the situation above ${\mathrm{T}}_{\mathrm{c}}$. Several features of the crossover are described. The difference between the T=0 ``pair size'' and the (prefactor of the T dependent) Ginzburg-Landau coherence length is pointed out: the two quantities are the same only in the BCS limit. The evolution of the collective modes from the BCS to the Bose regime is discussed together with the mixing of the amplitude and phase in the absence of a particle-hole symmetry.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
