Abstract
We show that a (2+1)-dimensional Chern-Simons gauge theory where the gauge field couples to flavored fermions (i.e., fermions carrying an auxiliary quantum number) arises in a natural way from a chiral two-band model describing the dynamical Jahn-Teller effect. The theory exhibits finite-temperature superconductivity without Cooper pairing and a second-order phase transition.
