Rectangular Potentials in a Semi-Harmonic Background: Spectrum, Resonances and Dwell Time
Nicolás Fernández-García, Oscar Rosas-Ortiz
We study the energy properties of a particle in one dimensional semi-harmonic rectangular wells and barriers. The integration of energies is obtained by solving a simple transcende…

Optical potentials using resonance states in Supersymmetric Quantum Mechanics
N. Fernandez-Garcia, O. Rosas-Ortiz
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…

Gamow-Siegert functions and Darboux-deformed short range potentials
Nicolas Fernandez-Garcia, Oscar Rosas-Ortiz
Darboux-deformations of short range one-dimensional potentials are constructed by means of Gamow-Siegert functions (resonance states). Results include both Hermitian and non-Hermit…
