Abstract
The phase portrait of dense quark matter is investigated within the (3 + 1)-dimensional Nambu—Jona-Lasinio model taking the isospin and chiral-isospin asymmetries in quarks into account. It is shown that the chiral-isospin chemical potential contributes to the generation of the phase with charged pion condensation.
