چکیده

This paper is devoted to the study of interactions between stationary electromagnetic sources for minimal and nonminimal CPT-odd photon sector Standard Model Extension (SME), where we search mainly physical phenomena not present in Maxwell electrodynamics. First consider sector, Lorentz violation caused by Carroll-Field-Jackiw (CFJ) term, namely $\sim\epsilon^{\mu\nu\alpha\beta}\left(k_{AF}\right)_{\mu}A_{\nu}F_{\alpha\beta}$, treat breaking parameter $\left(k_{AF}\right)^{\mu}$ perturbatively up second order. We effects due presence point-like charges, Dirac strings dipoles. In special, calculate field produced outside string investigate so called Aharonov-Bohm bound states context. After, a model generated higher-derivative version CFJ model, $\sim\epsilon^{\mu\nu\alpha\beta}V_{\mu}A_{\nu}\Box F_{\alpha\beta}$, which dimension five term SME. For this obtain order $V^{\mu}$ related charges steady current line. use overestimated constrains parameters relevance some results found atomic systems. also make an overestimate background vectors using experimental data from electric field.

On Dirac - like Monopoles in a Lorentz - and CPT - violating Electrodynamics

We study magnetic monopoles in a Lorentz-and CPT-odd electrodynamical framework in (3+1) dimensions. This is the standard Maxwell model extended by means of a Chern-Simons-like term, b µ ˜ F µν A ν (b µ constant), which respects gauge invariance but violates both Lorentz and CPT symmetries (as a consequence, duality is also lost). Our main interest concerns the analysis of the model in the pres...

Gauge Invariance and the Pauli-Villars Regulator in Lorentz- and CPT-Violating Electrodynamics

We examine the nonperturbative structure of the radiatively induced Chern-Simons term in a Lorentzand CPT-violating modification of QED. Although the coefficient of the induced Chern-Simons term is in general undetermined, the nonperturbative theory appears to generate a definite value. However, the CPT-even radiative corrections in this same formulation of the theory generally break gauge inva...

Classical Solutions in a Lorentz-violating Scenario of Maxwell-Chern-Simons-Proca Electrodynamics

Taking as starting point the planar model that arises from the dimensional reduction of the Abelian-Higgs Carroll-Field-Jackiw model, we write down and study the extendedMaxwell equations and the associated wave equations for the potentials. The solutions for these equations correspond to the usual ones for the MCS-Proca system, supplemented with background-dependent correction terms. In the ca...

Electrostatic and Magnetostatic Solutions in a Lorentz-Violating Electrodynamics Model

We propose an effective Lorentz violating electrodynamical model via static de Sitter metric which is deviated from Minkowski metric by a minuscule amount depending on the cosmological constant. We obtain the electromagnetic field equations via the vierbein decomposition of the tensors. In addition, as an application of the electromagnetic field equations obtained, we get the solutions of elect...

Photon decay in a CPT-violating extension of quantum electrodynamics

We consider the process of photon decay in quantum electrodynamics with a CPTviolating Chern–Simons-like term added to the action. For a simplified model with only the quadratic Maxwell and Chern–Simons-like terms and the quartic Euler– Heisenberg term, we obtain a nonvanishing probability for the decay of a particular photon state into three others.
