The non-minimal coupling of fermions to a background responsible for the breaking of
Lorentz symmetry is introduced in Dirac's equation; the non-relativistic regime is …

This paper deals with situations that illustrate how the violation of Lorentz symmetry in the
gauge sector may contribute to magnetic moment generation of massive neutral particles …

We consider QED in a constant axial vector background (Æther). Further Lorentz invariance
violations (LIV) might occur owing to radiative corrections. The phenomenology of this model …

The influence of a Lorentz-violating fixed background on fermions is considered by means of
a torsion-free nonminimal coupling. The nonrelativistic regime is assessed and the Lorentz …

In this paper, we formulate a theory of the second-rank antisymmetric (pseudo) tensor field
minimally coupled to a spinor; calculate the one-loop effective potential of the (pseudo) …

In this work, we study the spontaneous Lorentz symmetry breaking due to an antisymmetric
2-tensor field in Minkowski spacetime. For a smooth quadratic potential, the spectrum of the …

We show for the first time that the induced parity-even Lorentz invariance violation can be
unambiguously calculated in the physically justified and minimally broken, dimensional …

The influence of Lorentz-and CPT-violating terms (in" vector" and" axial vector" couplings)
on the Dirac equation is explicitly analyzed: plane-wave solutions, dispersion relations and …

We study the quantization of a simple model of antisymmetric tensor field with spontaneous
Lorentz violation in curved spacetime. We evaluate the one-loop corrections at first order of …

In theories with extra dimensions it is well known that the Lorentz invariance of the D= 4+ n-
dimensional spacetime is lost due to the compactified nature of the n dimensions leaving …
