Fourth order superintegrable quantum systems and Painlev茅 transcendents.

We consider two-dimensional quantum Superintegrable Hamiltonians with separation of variables in Cartesian coordinates. We focus on systems that allow fourth-order integrals of motion, also potentials satisfying nonlinear ODEs with the Painlev茅 property. We classify all potentials expressed in terms of Painlev茅 transcendents and their integrals.pav
