Additive and multiplicative noises acting simultaneously on Ermakov-Ray-Reid systems
(2016)
"We investigate numerically the effect of additive and multiplicative noises on parametric oscillator systems of Ermakov-Ray-Reid type when both noises act simultaneously. We find that the main perturbation effects on the ...
Ermakov-Ray-Reid systems with additive noise
(2015)
"Using the methods developed by us in Cervantes-López et al. (2014) for multiplicative noises, we present results on the effects of the additive noise on the Ermakov-Lewis invariant. This case can be implemented in the ...
Comment on demystifying the constancy of the Ermakov-Lewis invariant for a time-dependent oscillator
(World Scientific Publishing Company, 2018)
"We show that a simple modification of the Lagrangian proposed by Padmanabhan in the paper [Mod. Phys. Lett. A33, 1830005 (2018)] leads to the most general dynamical invariant in [Ray and Reid, Phys. Lett. A71, 317 (1979)]."
Relativistic Rotating Electromagnetic Fields
(Hindawi, 2020)
"In this work, we consider axially symmetric stationary electromagnetic fields in the framework of special relativity. These fields have an angular momentum density in the reference frame at rest with respect to the axis ...
Vanishing Poynting Observers and Electromagnetic Field Classification in Kerr and Kerr-Newman Spacetimes
(Hindawi, 2022)
"We consider electromagnetic fields having an angular momentum density in a locally nonrotating reference frame in Schwarzschild, Kerr, and Kerr-Newman spacetimes. The nature of such fields is assessed with two families ...
