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…

The DKP Equation in Presence of a Cusp Potential: Transmission Resonances and Bound States
Vicente A. Arévalo, Sebastián Valladares, Clara Rojas
In this article, we solve the Duffin--Kemmer--Petiau (DKP) equation in the presence of the cusp potential for spin--one particles. We derived the scattering solutions and calculate…
