We show that CPT-even aetherlike Lorentz-breaking actions, for the scalar and
electromagnetic fields, are generated via their appropriate Lorentz-breaking coupling to …

Magnetic moment generation from non-minimal couplings in a scenario with Lorentz-symmetry violation

H Belich, LP Colatto, T Costa-Soares… - The European Physical …, 2009 - Springer
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 …

Thermodynamics of a quantum ring modified by lorentz violation

AA Araújo Filho, H Hassanabadi, J Reis… - Physica …, 2023 - iopscience.iop.org

Bare and induced Lorentz and CPT invariance violations in QED

J Alfaro, AA Andrianov, M Cambiaso… - … Journal of Modern …, 2010 - World Scientific
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 …

CM Reyes - Physical Review D—Particles, Fields, Gravitation, and …, 2010 - APS
Stringent limits on the Myers-Pospelov timelike parameter for photons ξ< 10-15 coming from
astrophysical tests suggest exploring more general preferred backgrounds, such as …

Quantization of the Myers-Pospelov model: The photon sector interacting with standard fermions as a perturbation of QED

CM Reyes, LF Urrutia, JD Vergara - Physical Review D—Particles, Fields …, 2008 - APS
We study the quantization of the electromagnetic sector of the Myers-Pospelov model
coupled to standard fermions. Our main objective, based upon experimental and …

Unitarity in higher-order Lorentz-invariance violating QED

CM Reyes - Physical Review D—Particles, Fields, Gravitation, and …, 2013 - APS
The unitarity in Lorentz invariance violating QED consisting of standard fermions and higher-

M Frank, I Turan - Physical Review D—Particles, Fields, Gravitation, and …, 2006 - APS
We study the effects of the minimal extension of the standard model including Lorentz
violation on the Casimir force between two parallel conducting plates in the vacuum. We …

On the possibility of tree-level leptogenesis from Kalb–Ramond torsion background

M De Cesare, NE Mavromatos, S Sarkar - The European Physical Journal …, 2015 - Springer
