Negative time delay for wave reflection from a one-dimensional semi-harmonic well
Oscar Rosas-Ortiz, Sara Cruz y Cruz, Nicolas Fernandez-Garcia
It is reported that the phase time of particles which are reflected by a one-dimensional semi-harmonic well includes a time delay term which is negative for definite intervals of t…
Wronskian differential formula for confluent supersymmetric quantum mechanics
David Bermudez, David J. Fernandez C., Nicolas Fernandez-Garcia
A Wronskian differential formula, useful for applying the confluent second-order SUSY transformations to arbitrary potentials, will be obtained. This expression involves a parametr…
Extended WKB method, resonances and supersymmetric radial barriers
Nicolas Fernandez-Garcia, Oscar Rosas-Ortiz
Semiclassical approximations are implemented in the calculation of position and width of low energy resonances for radial barriers. The numerical integrations are delimited by t/T<…
A Primer on Resonances in Quantum Mechanics
O. Rosas-Ortiz, N. Fernandez-Garcia, Sara Cruz y Cruz
After a pedagogical introduction to the concept of resonance in classical and quantum mechanics, some interesting applications are discussed. The subject includes resonances occurr…
Higher-order supersymmetric quantum mechanics
David J Fernandez C, Nicolas Fernandez-Garcia
We review the higher-order supersymmetric quantum mechanics (H-SUSY QM), which involves differential intertwining operators of order greater than one. The iterations of first-order…
