What is Two-dimensional von Neumann--Wigner potentials with a multiple positive eigenvalue about?

By the Moutard transformation method we construct two-dimensional Schrodinger operators with real smooth potential decaying at infinity and with a multiple positive eigenvalue. These potentials are rational functions of spatial variables and their sines and cosines.
