Abstract In this paper, we study the one-loop effective potential of a derivative four-fermion model. As a result, an exact bumblebee-like potential is radiatively generated. Afterwards, we generalize our study for a finite temperature case and expli

Abstract In this paper, we explicitly calculate the lower CPT-even one-loop quantum corrections in nonminimal Lorentz-violating spinor QED with all possible CPT-even dimension-5 operators. Within our calculations, we restrict ourselves to the cases w

Abstract In this paper, we explicitly calculate the aether-like corrections for the electromagnetic field in the case when the space-time involves an extra compact spatial dimension besides of usual four dimensions. Our methodology is based on an exp

In this paper, we demonstrate the possibility of generating a non-Abelian Carroll–Field–Jackiw (CFJ) term in the theory of a non-Abelian gauge field coupled to a spin-3/2 field in the presence of the constant axial vector field. Applying two regu

Abstract We consider the Lorentz-violating extended QED involving all nonminimal dimension-5 additive CPT-odd terms. For this theory, we investigate the generation of the Carroll–Field–Jackiw (CFJ) term and its higher-derivative counterparts of t

Abstract We study a class of four-fermion Gross–Neveu like models in four dimensions with critical exponents $$z=2$$ z=2 and $$z=3$$ z=3 . The models with $$z=2$$ z=2 are in general perturbatively nonrenormalizable but we show that there are in spe

Abstract We consider the four-fermion Lifshitz model, introduce in this model an auxiliary vector field, and generate an effective dynamics for this field. We explicitly demonstrate that within this dynamics, the effective bumblebee potential for the

In this work we study the dynamical generation of mass in the Lorentz-violating low-dimensional super-Yang–Mills theory in the aether superspace coupled to a scalar matter. We also suggest that our studies can be applied for condensed matter system

Abstract We 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.

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.
