Short survey of Darboux transformations
H. C. Rosu
A selective chronological survey of Darboux transformations as related to supersymmetric quantum mechanics, intertwining operators and inverse scattering techniques is presented. S…
Strictly isospectral SUSY potentials and the Riccati superposition principle
H. C. Rosu
The connection of unbroken SUSY quantum mechanics in its strictly isospectral form with the nonlinear Riccati superposition principle is pointed out
q deformation by intertwining with application to the singular oscillator
H. C. Rosu, C. Castro
We present a version of q-deformed calculus based on deformed counterparts of Darboux intertwining operators. The case in which the deformed transformation function is of the vacuu…
Quantum Mechanics: I
H. C. Rosu
This is the first Internet course on elementary quantum mechanics written in Spanish ("castellano") for the benefit of Spanish speaking students. I thank my eight Mexican students…
Ermakov approach for empty FRW minisuperspace oscillators
H. C. Rosu
The formal Ermakov approach for empty FRW minisuperspace cosmological models of arbitrary Hartle-Hawking factor ordering and the corresponding squeezing features are briefly discus…
Using strictly isospectral unbroken nonrelativistic supersymmetry as a toy model
H. C. Rosu
I employ heuristically the strictly isospectral double Darboux method based on the general superpotential of unbroken nonrelativistic supersymmetry suggesting a few small steps of…
