(Springer) For the first time, a team of mathematical physicists from Togo and Benin, call upon supersymmetry to explain the behaviour of particles that have received a photon and are subjected to particular potential energies known as shape-invariant potentials. In a paper published in EPJD, Komi Sodoga and colleagues affiliated with both the University of Lomé, Togo, and the University of Abomey-Calavi, in Cotonou, Benin, outline the details of their theory, which is useful for quantum optics and quantum mechanics applications.
