Classical and quantum superintegrable systems on the sphere and the hyperbolic 2-space

open access: yesActa Polytechnica
We present two superintegrable Hamiltonian systems in two dimensions, defined on the sphere and on the hyperbolic plane. These systems are generalised à la Tremblay-Turbiner-Winternitz (TTW), involving the introduction of a real parameter k > 0, with ...
