The superradiance phenomenon in spin-one particles
Sebastian Valladares, Clara Rojas
In this article, we solve the Duffin--Kemmer--Petiau (DKP) equation in the presence of hyperbolic tangent potential for spin-one particles. By partitioning the spin-one spinor, we…
Study of the Klein--Gordon equation for a hydrogenic model of dyons
Edison Fernando García Veloz, Clara Rojas
This article presents the generalization of a zero spin hydrogen atom to a relativistic atomic model of hydrogen with dyons using the Klein--Gordon equation. The derivation of the…
Inflation from a chaotic potential with a step
Clara Rojas, Rafael Hernández-Jiménez
In this work, we study the effects on the relevant observational parameters of an inflationary universe from a chaotic potential with a step. We numerically evolve the perturbation…
Study of scalar and tensor power spectra in the generalized Starobinsky inflationary model using semiclassical methods
Clara Rojas
In this work we solved the equation of scalar and tensor perturbations for the generalized Starobinsky inflationary model using the improved uniform approximation method and the ph…
Numerical analysis of the generalized Starobinsky inflationary model
Stefano Meza, David Altamirano, Muhammad Zahid Mughal +1
In this work we study numerically one kind of generalization of the Starobinsky inflationary model (power-law type), which is characterized by the parameter . In order to find t…
Bound states of a Klein-Gordon particle in presence of a smooth potential well
Eduardo López, Clara Rojas
We solve the one-dimensional time-independent Klein-Gordon equation in presence of a smooth potential well. The bound state solutions are given in terms of the Whittaker $M_{κ,μ}(x…
