# Nambu-Jona-Lasinio model description of weakly interacting Bose condensate and BEC-BCS crossover in dense QCD-like theories

@article{He2010NambuJonaLasinioMD, title={Nambu-Jona-Lasinio model description of weakly interacting Bose condensate and BEC-BCS crossover in dense QCD-like theories}, author={Lianyi He}, journal={Physical Review D}, year={2010}, volume={82}, pages={096003} }

QCD-like theories possess a positively definite fermion determinant at finite baryon chemical potential ${\ensuremath{\mu}}_{B}$ and the lattice simulation can be successfully performed. While the chiral perturbation theories are sufficient to describe the Bose condensate at low density, to describe the crossover from Bose-Einstein condensation (BEC) to BCS superfluidity at moderate density we should use some fermionic effective model of QCD, such as the Nambu--Jona-Lasinio model. In this paper…
