Uses gauge-invariant, path-dependent variables formalism

Provides insights into the interaction structure of topologically massive Born-Infeld theory

Abstract

For a (2+1)-dimensional topologically massive Born-Infeld theory, we compute the interaction potential within the structure of the gauge-invariant but path-dependent variables formalism. The result is equivalent to that of $QED_3$ with a Thirring interaction term among fermions, in the short distance regime.
