Description
In this talk, I discuss a lattice Nambu–Jona-Lasinio model with certain continuous chiral and two-flavor symmetries.
For the Hamiltonian of this model, we construct a ground state that simultaneously breaks parity and flavor symmetries.
This phase structure may be viewed as analogous to the Aoki phase, although the model does not contain a Wilson term.
