A perfectly conducting surface in electrodynamics with Lorentz symmetry breaking
(2017-10-01)
In this paper we consider a model which exhibits explicit Lorentz symmetry breaking due to the presence of a single background vector vμ coupled to the gauge field. We investigate such a theory in the vicinity of a perfectly ...
Mirrors and field sources in a Lorentz-violating scalar field theory
(2020-05-01)
In this paper we consider classical effects in a model for a scalar field incorporating Lorentz symmetry breaking due to the presence of a single background vector vμ coupled to its derivative. We investigate of the ...
Momento oculto em sistemas quânticos e sua relação com o momento da luz na matéria
(Universidade Federal de Minas GeraisUFMG, 2016-06-30)
In a recent paper, Mansuripur presented an apparent paradox that seemed to imply that the Lorentz force is incompatible with special relativity and momentum conservation. However, it was shown that this paradox disappears ...
Stochastic PDEs, random fields and exact mean-values
(IOP Publishing, 2020-10)
Introducing projector-operator technique and algebra of Terwiel's cumulants we study stochastic linear partial differential equations with global and local disorder. We present the evolution equation for the mean-value of ...
Effect of electromagnetic fields in the process of arc extinction in molded case circuit breakers
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2018-05-15)
The new computational tools developed in the last decade are a great contribution to solve complex problems related to the design of circuit breakers. In the past, the experimental research was almost the unique way to ...
Monopolos tipo-Dirac em uma eletrodinâmica com violação das simetrias de Lorentz e CPTOn Dirac-like monopoles in a Lorentz and CPT-violating electrodynamics

Electrodynamics and the electron equation of motion
(1976)
We show the extent to which Lorentz-Dirac equations of motion for the electron follow from Maxwell's equations. The standard derivations depend on cutoff procedures and other prescriptions. The conclusion is that the Lorentz ...
