Abstract:
In this work we studied the classical and quantum aspects of derivative extension
of the Chern-Simons Abelian model in electro dynamics in (2+1) dimensions. In classical
context, we describe their main properties such as gauge in variance and the structure of
the associated propagator when this template is added to Maxwell's theory. The main
feature of this model is that it provides us a pair of excitation (one not massive and
another massive) for the propagation mode of the electromagnetic waves. In the quantum
context, we studied the possibility of inducing this term in thee active action of quantum
electrodynamics via radiative corrections of fermionic determinant in loop. In this case,
we analyze its occurrence at zero and nite temperature. The result a rising from the nite
temperature has the property to generate new excitement for the modes of propagation of electromagnetic waves dependent of temperature.
