The Phase Structure of Two Color QCD and Charged Pion Condensation Phenomenon

The phase structure of dense quark matter in the two color case has been investigated with nonzero baryon $${{\mu }_{{\text{B}}}}$$ , isospin }_{{\text{I}}}}$$ and chiral }_{{{\text{I5}}}}}$$ chemical potentials. It shown mean-field approximation that there exist three dualities, one them between phases spontaneous symmetry breaking condensation charged pions, found case. other dual symmetries pions diquark phenomena. demonstrated due to duality properties diagram is extremely symmetric whole can be obtained just by dualities from This shows are rather usefull tool. imbalance generates pion phenomenon conditions neutron stars, i. e. electrically neutral $$\beta $$ -equilibrated matter. And does not prohibit generation PC at least
