The confluent supersymmetry algorithm for Dirac equations with pseudoscalar potentials
Alonso Contreras-Astorga, Axel Schulze-Halberg
We introduce the confluent version of the quantum-mechanical supersymmetry (SUSY) formalism for the Dirac equation with a pseudoscalar potential. Application of the formalism to sp…

Painlevé IV Coherent States
David Bermudez, Alonso Contreras-Astorga, David J. Fernández C
A simple way to find solutions of the Painlevé IV equation is by identifying Hamiltonian systems with third-order differential ladder operators. Some of these systems can be obtain…
