We study the impact of Lorentz-violating terms on a physical observable for both electrodynamics of chiral matter and an Abelian Higgs-like model in 
dimensions. Our calculation is done within the framework of the gauge-invariant, but path-dependent, variables formalism. Interestingly enough, for electrodynamics of chiral matter we obtain a logarithmic correction to the usual static Coulomb potential. Whereas for an Abelian Higgs model with a Lorentz-breaking term, our result displays new corrections to the Yukawa potential.
