In this paper, the aether field, which leads to the violation of Lorentz symmetries, coupled with the electromagnetic field is considered. In order to study thermal and size effects in this theory, the thermofield dynamics (TFD) formalism is used. TFD is a real-time quantum field theory that has an interesting topological structure. Here, three different topologies are taken, and then, three different phenomena are calculated. These effects are investigated considering that the aether field can point in different directions. The results obtained are compared with the usual results of the Lorentz invariant electromagnetic field.
