• Additive and multiplicative noises acting simultaneously on Ermakov-Ray-Reid systems 

      Cervantes López, Ernesto; Espinoza Padilla, Pedro Basilio; Gallegos Infante, Luis Armando; Rosu Barbus, Haret-Codratian (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 ...
    • Comment on demystifying the constancy of the Ermakov-Lewis invariant for a time-dependent oscillator 

      Gallegos Infante, Luis Armando; Rosu Barbus, Haret-Codratian (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)]."
    • Ermakov-Ray-Reid systems with additive noise 

      Cervantes López, Ernesto; Espinoza Padilla, Pedro Basilio; Gallegos Infante, Luis Armando; Rosu Barbus, Haret-Codratian (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 ...
    • Relativistic Rotating Electromagnetic Fields 

      Vargas Rodríguez, Hector; Gallegos Infante, Luis Armando; Muñiz Torres, Miguel Angel; Rosu Barbus, Haret-Codratian; Domínguez Chávez, Paulino Javier (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 ...
