An Integrodifferential Equation for Electromagnetic Fields in Linear Dispersive Media
V. A. Coelho, F. S. S. Rosa, Reinaldo de Melo e Souza +2
We extend the usual derivation of the wave equation from Maxwell's equations in vacuum to the case of electromagnetic fields in dispersive homogeneous isotropic linear media. Usual…
Past and future blurring at fundamental length scale
M. J. Neves, C. Farina, M. V. Cougo-Pinto
We obtain the -deformed versions of the retarded and advanced Green functions and show that their causality properties are blurred in a time interval of the order of a length pa…
Multipole radiation fields from the Jefimenko equation for the magnetic field and the Panofsky-Phillips equation for the electric field
R. de Melo e Souza, M. V. Cougo-Pinto, C. Farina +1
We show how to obtain the first multipole contributions to the electromagnetic radiation emited by an arbitrary localized source directly from the Jefimenko equation for the magnet…
Primitively divergent diagrams in -deformed scalar field with quartic self-interaction
M. J. Neves, C. A. A. de Carvalho, C. Farina +1
We obtain the primitively divergent diagrams in -deformed scalar field in four-dimensional spacetime with quartic self-interaction in order to investigate the effect of the fund…
Effective action in DSR1 quantum field theory
M V Cougo-Pinto, C Farina, F S S Rosa +1
We present the one-loop effective action of a quantum scalar field with DSR1 space-time symmetry as a sum over field modes. The effective action has real and imaginary parts and ma…
Kappa-deformed quantum field theory and Casimir effect
M. V. Cougo-Pinto, C. Farina, J. F. M. Mendes
We consider the quantization of a scalar kappa-deformed field up to the point of obtaining an expression for its vacuum energy. The expression is given by the half sum of the field…
