Abstract

The properties of two-flavored massive Nambu–Jona-Lasinio model in ( $1 + 1$ )-dimensional spacetime are investigated in the presence of isospin and quark number chemical potentials. The consideration is performed in the large- $N_{c}$ limit, where $N_{c}$ is the number of colored quarks. It is shown in the framework of this model that charged pion condensation phenomenon of dense quark/hadron isotopically asymmetric matter is rather a spatially inhomogeneous than a homogeneous one.
