Zero temperature chiral phase transition in (2+1)-dimensional QED with a Chern-Simons term

We investigate the zero temperature chiral phase transition in (2 + 1)-dimensional QED in the presence of a Chern-Simons term, changing the number of fermion flavors. In the symmetric phase, there are no light degrees of freedom even at the critical point. Unlike the case without a Chern-Simons term, the phase transition is first order.
