Numerical Study of Some Generalizations of the Starobinsky Inflationary Model
Jordan Zambrano, Ángel Rodríguez, Melisa Alvear +1
In this work, we perform a numerical study of three Starobinsky--type inflationary scenarios: the --Starobinsky inflationary model, the power--law Starobinsky inflationary model…
Study of the Superradiance Phenomenon in the --attractor Potential using the Log Derivative Method
Ángel Salazar, Quray Potosí, David Laroze +3
In this article, we solved the time--independent one--dimensional Klein--Gordon equation in the presence of --attractor potential using the Log derivative method. We calculated…
The DKP Equation in Presence of a Woods-Saxon Potential: Transmission Resonances and Bound States
Alexis Garzón, Ricardo Fernández, Vicente A. Arévalo +4
In this article, we solve the Duffin-Kemmer-Petiau (DKP) equation in the presence of the Woods-Saxon potential barrier and well for spin-one particles. We derive the scattering sol…
Time evolution of Von Neumann entropy for a Kerr-Taub-NUT black hole
Vicente A. Arévalo, David Andrade, Clara Rojas
In this work, we study the evolution of an evaporating black hole, described by the Kerr--Taub--NUT metric, which emits scalar particles. We found that allowing the black hole to r…
