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…

Comments on: ``Weinberg's Nonlinear Quantum Mechanics and Einstein-Podolsky-Rosen paradox'', by Joseph Polchinski
Bogdan Mielnik
Contrary to the opinion of J. Polchinski [Phys.Rev.Lett. {\bf 66}, 397-400 (1991)], the phenomenon of superluminal messages in nonlinear versions of quantum mechanics is not a spec…
