Hydrogen atom as an eigenvalue problem in 3D spaces of constant curvature and minimal length
L. M. Nieto, H. C. Rosu, M. Santander
An old result of A.F. Stevenson [Phys. Rev.} 59, 842 (1941)] concerning the Kepler-Coulomb quantum problem on the three-dimensional (3D) hypersphere is considered from the perspect…
Quantum mechanical spectral engineering by scaling intertwining
D. J. Fernandez C., H. C. Rosu
Using the concept of spectral engineering we explore the possibilities of building potentials with prescribed spectra offered by a modified intertwining technique involving operato…
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…
Multiple parameter structure of Mielnik's isospectrality in unbroken SUSYQM
H. C. Rosu
Within unbroken SUSYQM and for zero factorization energy, I present an iterative generalization of Mielnik's isospectral method by employing a Schroedinger true zero mode in the fi…
