Nonlocal supersymmetric deformations of periodic potentials
David J. Fernandez C., Bogdan Mielnik, Oscar Rosas-Ortiz +1
Irreducible second-order Darboux transformations are applied to the periodic Schrodinger's operators. It is shown that for the pairs of factorization energies inside of the same fo…

Supersymmetrically transformed periodic potentials
David J. Fernandez C
The higher order supersymmetric partners of a stationary periodic potential are studied. The transformation functions associated to the band edges do not change the spectral struct…
