We calculate the perturbative correction to every cluster coefficient of a gas of anyons through second order in the anyon coupling constant, as described by Chern-Simons field theory.

Theories with gauge fields coupled to matter fields in (2+1) space dimensions present novel effects as compared to the (3+1) dimensional case. In planar systems the Chern-Simons term (CS) can supplement (sometimes replace) the Maxwell term in the action for the gauge field [1] . Additionally, the covariant coupling to the scalar field can be modified by the inclusion of an extra term, which is ...

We calculate by the method of dimensional regularization and derivative expansion the one-loop effective action for a Dirac fermion with a Lorentz-violating and PCT-odd kinetic term in the background of a gauge field. We show that this term induces a Chern-Simons modification to Maxwell theory. Some related issues are also discussed.

We consider the (2 + 1)-dimensional massive Thirring model as a gauge theory, with one fermion flavor, in the framework of the causal perturbation theory and address the problem of dynamical mass generation for the gauge boson. In this context we get an unambiguous expression for the coefficient of the induced Chern-Simons term.
