Possible crossover from BCS superconductivity to Bose-Einstein condensate in quark matter
نویسنده
چکیده
The possibility of the crossover from the BCS pairing to the Bose-Einstein condensate (BEC) of diquarks with going down in density is discussed in the framework of in the Nambu Jona-Lasinio (NJL) model. We find that the quark matter at moderate density may be close to the intermediate of the crossover, the precursory regime to the BEC phase.

Se p 20 04 Klein – Gordon Equation for Quark Pairs in Color Superconductor
The wave equation is derived for quark pairs in color superconductor in the regime of low density/strong coupling. During the last five years color superconductivity became a compelling topic in QCD – see the review papers [1]. Grossly speaking, we have a fair understanding of color superconductivity physics in the high den-sity/weak coupling regime. In the low density/strong coupling region th...
متن کاملCrossover from BCS to BEC ? —
We discuss a possibility of transition from color superconductivity of the standard BCS type at high density, to Bose-Einstein Condensation (BEC) of Cooper pairs at lower density. Examining two-flavor QCD over a wide range of baryon density, we found the size of a Cooper pair becomes small enough to be comparable to the averaged quark-quark distance at lower density. We also consider the same p...

We argue that there is a unique transition state of moderate density between the nuclear matter and superconducting quark matter alternatives. The distinguishing features of this state are discussed. During the last years, the investigation of quark matter at finite temperature and density has become one of the QCD focal points. Based on model calculations it has been predicted that at densitie...
متن کاملcondensates in quark and atomic systems ∗
In these lectures we discuss condensates which are formed in quark matter when it is squeezed and in a gas of fermionic atoms when it is cooled. The behavior of these two seemingly very different systems reveals striking similarities. In particular, in both systems the Bose-Einstein condensate to Bardeen–Cooper-Schrieffer (BEC-BCS) crossover takes place.

The physics of the crossover between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-coupling Bose-Einstein condensate (BEC) limits gives a unified framework of quantum-bound (superfluid) states of interacting fermions. This crossover has been studied in the ultracold atomic systems, but is extremely difficult to be realized for electrons in solids. Recently, the superconducting semime...
