Weak dual symmetries of two color QCD phase diagram

Abstract

The phase diagram of two color QCD under influence of baryon density (${\mu }_B$), isospin (${\mu }_I$), chiral (${\mu }_5$ and ${\nu }_5$) imbalances is investigated within the framework NJL model approach. This letter establishes the existence of weak dualities in two color quark matter--symmetries revealed when full thermodynamic potential is projected or restricted to specific condensation channels. These dualities provide a unified understanding of two interesting phenomena in the phase diagram: universal catalysis and chameleon effect of chiral chemical potential.
