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… 
Optimized perturbation theory applied to the study of the thermodynamics and BEC-BCS crossover in the three-color Nambu-Jona-Lasinio model
The Nambu--Jona-Lasinio model with two flavors, three colors and diquark interactions is analyzed in the context of optimized perturbation theory (OPT). Corrections to the thermodynamical potential
Holographic Floquet states II: Floquet condensation of vector mesons in nonequilibrium phase diagram
A bstractWith the aim to reveal universal features of hadronic matter and correlated Dirac insulators in strong AC-electric fields, we study the N=2$$ \mathcal{N}=2 $$ supersymmetric QCD with a
BCS–BEC crossover and stability in a Nambu–Jona-Lasinio model with diquark–diquark repulsion
Abstract We investigate the equation of state (EoS) along the BCS–BEC crossover for a quark system described by a Nambu–Jona-Lasinio model with multi-fermion interactions. Together with attractive
Quantum fluctuations in the BCS-BEC crossover of two-dimensional Fermi gases
We present a theoretical study of the ground state of the BCS-BEC crossover in dilute two-dimensional Fermi gases. While the mean-field theory provides a simple and analytical equation of state, the
Two-colour QCD phases and the topology at low temperature and high density
We delineate equilibrium phase structure and topological charge distribution of dense two-colour QCD at low temperature by using a lattice simulation with two-flavour Wilson fermions that has a
Phase diagram of two-color QCD in a Dyson-Schwinger approach
We investigate two-color QCD with two flavors at finite temperatures and chemical potentials using a Dyson-Schwinger approach. We employ two different truncations for the quark loop in the gluon DSE:
A proposal of a renormalizable Nambu–Jona-Lasinio model
A local and gauge invariant gauge field model including Nambu–Jona-Lasinio (NJL) and QCD Lagrangian terms in its action is introduced. Surprisingly, it becomes power counting renormalizable. This
Phase diagram of dense two-color QCD within lattice simulations
We present the results of a low-temperature scan of the phase diagram of dense two-color QCD with Nf = 2 quarks. The study is conducted using lattice simulation with rooted staggered quarks. At small
QCD with Chemical Potential and Matrix Models
In the first section the dynamics of QCD at finite temperature and density are summarized. Color superconductivity that takes place at sufficiently high density and low temperature is reviewed and
Continuum Goldstone spectrum of two-color QCD at finite density with staggered quarks
We carry out lattice simulations of two-color QCD and spectroscopy at finite density with two flavors of rooted-staggered quarks and a diquark source term. As in a previous four-flavor study, for
