Self-Interacting Electromagnetic Fields and a Classical Discussion on the Stability of the Electric Charge
S. O. Vellozo, José A. Helayël-Neto, A. W. Smith +1
The present work proposes a discussion on the self-energy of charged particles in the framework of nonlinear electrodynamics. We seek magnet- ically stable solutions generated by p…
Magnetic Moment Generation from non-minimal couplings in a scenario with Lorentz-Symmetry Violation
H. Belich, L. P. Colatto, T. Costa-Soares +2
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…
Standstill Electric Charge Generates Magnetostatic Field Under Born-Infeld Electrodynamics
S. O. Vellozo, Jose A. Helayel-Neto, A. W. Smith +1
The Abelian Born-Infeld classical non-linear electrodynamic has been used to investigate the electric and magnetostatic fields generated by a point-like electrical charge at rest i…
Comparing Implicit, Differential, Dimensional and BPHZ Renormalisation
M. Sampaio, A. P. Baeta Scarpelli, B. Hiller +3
We compare a momentum space implicit regularisation (IR) framework with other renormalisation methods which may be applied to dimension specific theories, namely Differential Renor…
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…
Local Physical Coodinates from Symplectic Projector Method
M. A. De Andrade, M. A. Santos, I. V. Vancea
The basic arguments underlying the symplectic projector method are presented. By this method, local free coordinates on the constrait surface can be obtained for a broader class of…
