Riccati nonhermiticity with application to the Morse potential
O. Cornejo-Perez, R. Lopez-Sandoval, H. C. Rosu
A supersymmetric one-dimensional matrix procedure similar to relationships of the same type between Dirac and Schrodinger equations in particle physics is described at the general…
Cyclotomic quantum clock
H. C. Rosu, M. Planat
In the wake of our recent work on cyclotomic effects in quantum phase locking [M. Planat and H. C. Rosu, Phys. Lett. A 315, 1 (2003)], we briefly discuss here a cyclotomic extensio…
On first-order scaling intertwining in quantum mechanics
D. J. Fernandez C., H. C. Rosu
We generalize the standard first-order intertwining relationship of supersymmetric quantum mechanics in order to include simultaneous scaling transformations in both the original H…
Strictly isospectral potentials from excited quantum states
R. Klippert, H. C. Rosu
The strictly nonrelativistic isospectral scheme based on the general Riccati solution and Darboux transformation function corresponding to excited states is presented on the follow…
On a SUSY QM scheme for any linear homogeneous differential equation of the second order
R. Klippert, H. C. Rosu
A formal SUSY QM procedure for any linear homogeneous second-order differential equation is briefly sketched up and applied to a simple exactly solvable case
Between Schroedinger and Hermite: Supersymmetric pair of q-deformed non-local operators
H. C. Rosu
A simple version of the q-deformed calculus is used to generate a pair of q-nonlocal, second-order difference operators by means of deformed counterparts of Darboux intertwining op…
