Abstract
e1em Se estudia la teoría de Maxwell-Chern-Simons con un acoplamiento con un campo gravitacional en el vacío y en presencia de un medio óptico simple que permea una región consi-derablemente grande del espacio, a través de la introducción de la métrica óptica de Gordon. Se escribe la acción de la teoría en un espacio-tiempo general, se obtienen las ecuaciones de campo, y se hallan generalizaciones de la ecuación de Klein-Gordon para cada caso. Luego se exploran los casos de espacio-tiempos maximalmente simétricos, donde se obtienen ecuaciones de onda masiva para el tensor de campo electromagnético. Un resultado peculiar es que en los espacio-tiempos de de Sitter en presencia de un medio óptico, la parte eléctrica del tensor de campo exhibe una masa diferente de la masa de la parte magnética
We study the Maxwell-Chern-Simons theory coupling it to a gravitational field in a va-cuum and under the presence of a simple optical medium that permeates a considerably large region of space, by means of the introduction of the Gordon optical metric. We describe the action of the theory, derive the field equations, and obtain generalizations of the Klein-Gordon equation for each case. Then we explore the cases of maximally symmetric space time, where we obtain massive wave equations for the electromagnetic field tensor. A particularly interesting result is that in the de Sitter family of space time, under the presence of the optical medium, the electric part of the field tensor has a mass greater than the mass of the magnetic part
