Evolution loops and spin-1/2 systems
D. J. Fernandez C., O. Rosas-Ortiz
The derivation of a new family of magnetic fields inducing exactly solvable spin evolutions is presented. The conditions for which these fields generate the evolution loops (dynami…

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…
