Testing CPT- and Lorentz-odd electrodynamics with waveguides
A. H. Gomes, J. M. Fonseca, W. A. Moura-Melo +1
We study CPT- and Lorentz-odd electrodynamics described by the Standard Model Extension. Its radiation is confined to the geometry of hollow conductor waveguide, open along . In…
Emission and absorption of photons and the black-body spectra in Lorentz-odd Electrodynamics
J. M. Fonseca, A. H. Gomes, W. A. Moura-Melo
We study a number of issues related to the emission and absorption radiation by non-relativistic electrons within the framework of a Lorentz-breaking electrodynamics in (3+1) dimen…
On Dirac-like Monopoles in a Lorentz- and CPT-violating Electrodynamics
N. M. Barraz, J. M. Fonseca, W. A. Moura-Melo +1
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 te…
Remarks on Charged Vortices in the Maxwell-Chern-Simons Model
L. P. Colatto, J. A. Helayel-Neto, M. Hott +1
We study vortex-like configuration in Maxwell-Chern-Simons Electrodynamics. Attention is paid to the similarity it shares with the Nielsen-Olesen solutions at large distances. A ma…
Dirac-like Monopoles in Three Dimensions and Their Possible Influences on the Dynamics of Particles
E. M. C. Abreu, J. A. Helayel-Neto, M. Hott +1
Dirac-like monopoles are studied in three-dimensional Abelian Maxwell and Maxwell-Chern-Simons models. Their scalar nature is highlighted and discussed through a dimensional reduct…
Generalized Gauge Transformations and Regularized -type Abelian Vertices
Winder A. Moura-Melo, J. A. Helayel-Neto
Abelian Lagrangians containing -type vertices are regularized by means of a suitable point-splitting scheme combined with generalized gauge transformations. The calculation…
Huyghens Principle, Planck Law: Peculiarities in the Behavior of Planar Photons
Winder A. Moura-Melo, J. A. Helayel-Neto
Huyghens principle and Planck law are studied in Maxwell and Maxwell-Chern-Simons frameworks in (2+1) dimensions. Contrary to (3+1) dimensions, massless photons are shown to violat…
Remarks on Dirac-like Monopole, Maxwell and Maxwell-Chern-Simons Electrodynamics in D=(2+1)
Winder A. Moura-Melo, J. A. Helayël-Neto
Classical Maxwell and Maxwell-Chern-Simons (MCS) Electrodynamics in (2+1)D are studied in some details. General expressions for the potential and fields are obtained for both model…
On Massive Vector Bosons and Abelian Magnetic Monopoles in D=(3+1): a Possible Way to Quantise the Topological Mass Parameter
Winder A. Moura-Melo, N. Panza, J. A. Helayel-Neto
An Abelian gauge model, with vector and 2-form potential fields linked by a topological mass term that mixes the two Abelian factors, is shown to exhibit Dirac-like magnetic monopo…
Generalized Gauge Transformations and Regularized -type Abelian Vertices
Winder A. Moura-Melo, J. A. Helayel-Neto
Abelian Lagrangians containing Phi^4-type vertices are regularized by means of a suitable point-splitting scheme combined with generalized gauge transformations.. The calculation i…
