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…
Gamow vectors and Supersymmetric Quantum Mechanics
Oscar Rosas-Ortiz
Gamow solutions are used to transform self-adjoint energy operators by means of factorization (supersymmetric) techniques. The transformed non-hermitian operators admit a discrete…
On susy periodicity defects of the Lame Potentials
Oscar Rosas-Ortiz
The supersymmetric Quantum Mechanics approach is applied to embed bound states in the energy gaps of periodic potentials. The mechanism to generate periodicity defects in the first…
Physical sectors of the confluent hypergeometric functions space
O. Rosas-Ortiz, J. Negro, L. M. Nieto
A relaxed factorization is used to obtain many of the properties obeyed by the confluent hypergeometric functions. Their implications on the analytical solutions of some interestin…
