Infinite families of superintegrable and exactly solvable systems in a Euclidean plane

Abstract: Two infinite families of exactly solvable and superintegrable potentials on a plane are introduced. Both depend on an integer or rational parameter k and allow the separation of variables in polar coordinates. One is a deformation of the isotropic harmonic oscillator, the other of the Coulomb- Kepler potential. The underlying algebraic structure of the new potentials is revealed as well as their underlying hidden algebra. In the quantum case we calculate the wave functions and energy spectrum with its degeneracy. In the classical one we calculate the bounded trajectories and show that they are all periodic, as required for a maximally superintegrable system.
