Influence of chiral asymmetry on phase structure of the two-color quark matter

Understand

In this paper the influence of chiral chemical potential $\mu_5$ on the phenomenon of diquark condensation and phase structure of dense quark matter altogether is contemplated in the framework of effective two-color and two-flavor Nambu--Jona-Lasinio model.

• We show that the duality relations, found $\mu_5=0$, are also valid for any value of $\mu_5\neq0$.
• Hence the dualities seem to be a real fundamental feature of the phase diagram of two color quark matter, and besides they are a very powerful tool of studying the phase structure.
• In terms of dualities and the influence on the phase diagram chiral imbalance $\mu_5$ stands alone from other chemical potentials.
