Remarks on Quantum Aspects of 3D-Gravity in the First-Order Formalism
L M de Moraes, J A Helayel-Neto, V J Vasquez Otoya
In this paper, we reassess the issue of working out the propagators and identifying the spectrum of excitations associated to the vielbein and spin connection of (1+2)-D gravity in…
Lorentz-violating corrections on the hydrogen spectrum induced by a non-minimal coupling
H. Belich, T. Costa-Soares, M. M. Ferreira +2
The influence of a Lorentz-violating fixed background on fermions is considered by means of a torsion-free non-minimal coupling. The non-relativistic regime is assessed and the Lor…
A Lorentz-violating SO(3) model: discussing the unitarity, causality and the 't Hooft-Polyakov monopoles
A. P. Baeta Scarpelli, J. A. Helayel-Neto
In this paper, we extend the analysis of the Lorentz-violating Quantum Eletrodynamics to the non-Abelian case: an SO(3) Yang-Mills Lagrangian with the addition of the non-Abelian C…
