Four-dimensional aether-like Lorentz-breaking QED revisited and problem of ambiguities

In this paper, we consider the perturbative generation of the CPT-even aether-like Lorentz-breaking term in the extended Lorentz-breaking QED within different approaches and discuss its ambiguities.

Free energy of Lorentz-violating QED at high temperature

In this paper we study the one- and two-loop contribution to the free energy in QED with Lorentz symmetry breaking introduced via constant CPT-even Lorentz-breaking parameters at the high temperature limit. We find the impact of the Lorentz-violating term for the free energy and carry out a numerical estimation for the Lorentz-breaking parameter.

On the radiative corrections in the Horava–Lifshitz z = 2 QED

Abstract We calculate one-loop contributions to the two and three point spinor–vector functions in z = 2 Horava–Lifshitz QED. This allows us to obtain the anomalous magnetic moment.

On one-loop corrections to the CPT-even Lorentz-breaking extension of QED

In this paper, we describe the generation of the CPT-even, aether-like terms via the new CPT-even magnetic-like coupling. We carry out a study the loop corrections generated by this coupling. Previous investigations has been initiated on this issue and we have extended them to studying of higher-point functions, of quantum corrections to vertices of the interaction and to two-point function of the spinor field.

Non-analyticity of the induced Carroll-Field-Jackiw term at finite temperature

A bstractWe calculate the linearized four-dimensional gravitational Chern-Simons term at the finite temperature, show its finiteness and explicitly demonstrate that its transversal part matches the known result for the chiral vortical conductivity.

On the Adler-Bell-Jackiw anomaly in a Horava-Lifshitz–like QED

In this paper, we describe the quantum electrodynamics added by Lorentz-violating CPT-even terms in the context of the standard model extension. We focus our attention on the fermion sector, represented by the CPT-even symmetric Lorentz-breaking tensor cμν. We adopt a generic form that parametrizes the components of cμν in terms of one four-vector, namely, cμν = uμuν − ζ u2 4 gμν. We then generate perturbatively, up to the third order in this tensor, the aether-like term for the gauge field. Finally, we discuss the renormalization scheme for the gauge propagator, by taking into account cμν traceless (ζ = 1) and, trivially, cμν = uμuν (ζ = 0).In this paper, we describe the quantum electrodynamics added by Lorentz-violating CPT-even terms in the context of the standard model extension.
