In science:

Within the current approximation (treating ms 6= 0 as a shift of the chemical potential), the action does not mix the left-handed quark and the right handed quarks.
Enforced neutrality and color-flavor unlocking in the three-flavor Polyakov-loop NJL model
Unfortunately progress in lattice QCD calculations has got severely hampered due to the QCD action becoming complex on account of the fermion sign problem when baryon density/chemical potential is non zero.
