Causality, unitarity, and indefinite metric in Maxwell-Chern-Simons extensions
Ricardo Avila, Jose R. Nascimento, Albert Yu. Petrov +2
We canonically quantize -dimensional electrodynamics including a higher-derivative Chern-Simons term. The effective theory describes a standard photon and an additional degr…
Formal Developments for Lorentz-Violating Dirac Fermions and Neutrinos
J. A. A. S. Reis, M. Schreck
The current paper is a technical work that is focused on Lorentz violation for Dirac fermions as well as neutrinos, described within the nonminimal Standard-Model Extension. We int…
(Gravitational) Vacuum Cherenkov Radiation
Marco Schreck
This work reviews our current understanding of Cherenkov-type processes in vacuum that may occur due to a possible violation of Lorentz invariance. The description of Lorentz viola…
Dimensional reduction of the electromagnetic sector of the nonminimal Standard-Model-Extension
Manoel M. Ferreira, João A. A. S. Reis, Marco Schreck
In the current paper, we construct a Lorentz-violating electrodynamics in (1+2) spacetime dimensions from the electromagnetic sector of the nonminimal Standard-Model Extension (SME…
Classical Lagrangians for the nonminimal Standard-Model Extension at higher orders in Lorentz violation
M. Schreck
The current paper is dedicated to determining perturbative expansions for Lagrangians describing classical, relativistic, pointlike particles subject to Lorentz violation parameter…
Maxwell electrodynamics modified by a CPT-odd dimension-five higher-derivative term
Manoel M. Ferreira, Letícia Lisboa-Santos, Roberto V. Maluf +1
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 th…
