This work tabulates measured and derived values of coefficients for Lorentz and CPT
violation in the standard-model extension. Summary tables are extracted listing maximal …

We propose a correspondence between the description of emergent Lorentz symmetry in
condensed-matter systems and the established general effective field theory for Lorentz …

Many effective field theories describing gravity cannot arise from an underlying theory based
on Riemann geometry or its extensions to include torsion and nonmetricity but may instead …

We investigate the behaviour of a massive scalar field under the influence of a Coulomb‐
type and central linear central potentials inserted in the Klein‐Gordon equation by modifying …

We investigated the relativistic oscillator model for spin-1/2 fermionic fields, known as the
Dirac oscillator, in a background of breaking the Lorentz symmetry governed by a constant …

In this paper, we investigate an electrodynamics in which the physical modes are coupled to
a Lorentz-violating background by means of a higher-derivative term. We analyze the modes …

A bstract We address the question whether a violation of Lorentz symmetry can explain the
tension between the measurement and the Standard-Model prediction of the anomalous …

In this paper, we consider an electrodynamics of higher derivatives coupled to a Lorentz-
violating background tensor. Specifically, we are interested in a dimension-five term of the …

We have investigated the relativistic quantum dynamics of a scalar field in an anisotropic
background governed by the Lorentz symmetry violation. This analysis is done through a …

This paper is devoted to the study of interactions between stationary electromagnetic
sources for the minimal and nonminimal CPT-odd photon sector of the Standard Model …
