Abstract Not all complete set of spinors can be used as expansion coefficients of a quantum field. In fact, Steven Weinberg established the uniqueness of Dirac spinors for this purpose provided: (a) one paid due attention to the multiplicative phases

As teorias de vínculos são de grande interesse na física teórica, pois todas as teorias conhecidas das interações fundamentais apresentam liberdade de calibre, que é um tipo de caráter singular da teoria, o que implica que ela possui vínculo

Abstract Bopp–Podolsky electrodynamics is generalized to curved space-times. The equations of motion are written for the case of static spherically symmetric black holes and their exterior solutions are analyzed using Bekenstein’s method. It is s

Este trabalho tem como objetivo introduzir a interpretação variacional de Schwinger ao fenômeno de Casimir, associada à construção de uma dinâmica quântica que descreva efetivamente a interação entre objetos macroscópicos (2 fontes) do pon

We study quantum electrodynamics (QED) in the light-front dynamical form by using null-plane causal perturbation theory. We establish the equivalence with instant dynamics for the scattering processes, whose normalization allows to construct the inst

In this paper, it is proposed a quantization procedure for the one-dimensional harmonic oscillator with time-dependent frequency, time-dependent driven force, and time-dependent dissipative term. The method is based on the construction of dynamical i

We develop a complete formulation of quantum gauge invariance in light-front dynamics for interacting theories with massless vector gauge fields in the framework of null-plane causal perturbation theory. We apply the general results to quantum electr
