We consider two self-dual Abelian Higgs systems obtained from Lorentz-breaking symmetry models by dimensional reduction. For the first model, we show that the self-dual equations are identical to those of Nielsen-Olesen ...

Inspired in discussions presented lately regarding Lorentz-violating interaction terms in B. Charneski, M. Gomes, R. V. Maluf and A. J. da Silva, Phys. Rev. D 86, 045003 (2012); R. Casana, M. M. Ferreira Jr., R. V. Maluf ...

E ective eld theory has shown to be a powerful method in searching for quantum gravity e ects and in particular for CPT and Lorentz symmetry violation. In this work we study an e ective eld theory with higher-order Lorentz ...

This paper is dedicated to the study of interactions between external sources for the electromagnetic field in a model which exhibits Lorentz-symmetry breaking. We investigate such interactions in the CPT-even photon sector ...

The full spectrum of two-dimensional fermion states in a scalar soliton trap with a Lorentz breaking background is investigated in the context of graphene, where the Lorentz symmetry should not be strictly valid. The field ...
