Optical potentials using resonance states in Supersymmetric Quantum Mechanics

Understand

Complex potentials are constructed as Darboux-deformations of short range, radial nonsingular potentials.

• They behave as optical devices which both refracts and absorbs light waves.
• The deformation preserves the initial spectrum of energies and it is implemented by means of a Gamow-Siegert function (resonance state).
• As straightforward example, the method is applied to the radial square well.
