Pion Condensation in Hot Dense Quark Matter with Isospin and Chiral-Isospin Asymmetries within the Nambu-Jona-Lasinio Model

摘要

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.
