摘要:
Using the supersymmetric method the quasi-exactly solvable (QES) periodic and random potentials with two known eigenstates have been constructed. The explicit examples of such potentials are presented. An interesting example is the QES disordered Kronig-Penney model for which we found in the explicit form the wave functions for two energy levels. (C) 2002 Elsevier Science B.V. All rights reserved.
