Two-dimensional Schrodinger Hamiltonians with effective mass in SUSY approach

摘要

The general solution of SUSY intertwining relations of first order for two-dimensional Schrodinger operators with position-dependent (effective) mass is built in terms of four arbitrary functions. The procedure of separation of variables for the constructed potentials is demonstrated in general form. The generalization for intertwining of second order is also considered. The general solution for a particular form of intertwining operator is found, its properties-symmetry. irreducibility, and separation of variables-are investigated. (C) 2008 Elsevier Inc.
