Аннотация
© 2020, Pleiades Publishing, Inc.The nonperturbative vacuum of quantum chromodynamics at a finite isospin chemical potential has been studied. Low-energy relations for the quark and gluon condensates have been derived ab initio. Analytical expressions for the quark and gluon condensates in the pion-condensate phase have been obtained at the tree level of the chiral perturbation theory. It has been shown that the quark condensate decreases with increasing μI, whereas the gluon condensate increases.
