abstract
We investigate chiral symmetry breaking and strong CP violation effects in the phase diagram of strongly interacting matter. We demonstrate the effect of strong CP violating terms on the phase structure at finite temperature and densities in a 3-flavor Nambu-Jona-Lasinio (NJL) model including the Kobayashi-Maskawa-t'Hooft (KMT) determinant term. This is investigated using an explicit structure for the ground state in terms of quark-antiquark condensates for both in the scalar and the pseudoscalar channels. CP restoring transition with temperature at zero baryon density is found to be a second order transition at $\theta = \pi$ while the same at finite chemical potential and small temperature turns out to be a first order transition. Within the model, the tri-critical point turns out to be $(T_c,\mu_c)\simeq(273,94)$ MeV at $\theta = \pi$ for such a transition.

On the $\theta$-angle physics of QCD under pressure: The strange and isospin phase diagram
The three-flavor QCD phase diagram at finite isospin and strangeness chemical potentials acquires a theta-dependence with a novel parity-preserving superfluid phase at theta = pi and no Dashen transition inside the su...

First-order CP phase transition in two-flavor QCD at $\theta = \pi$ under electromagnetic scale anomaly via a Nambu-Jona-Lasinio description
In an NJL model, the electromagnetic scale anomaly creates a thermal potential barrier proportional to |eB|^3 |P|/(P^2 + m0^2), making the theta = pi CP transition first order.

CP violation in cold dense quark matter and axion effects on the non-radial oscillations of neutron stars
Using a 3-flavor NJL model with axions, the authors find that a CP-violating angle theta=pi reduces the chiral transition density and, with a vector repulsion, yields stable hybrid neutron stars with enhanced f-mode o...
