Abstract: | We extend recent work by Tremblay, Turbiner, and Winternitz which analyzes an infinite family of solvable and integrable quantum
systems in the plane, indexed by the positive parameter k. Key components of their analysis were to demonstrate that there are closed orbits in the corresponding classical system
if k is rational, and for a number of examples there are generating quantum symmetries that are higher order differential operators
than two. Indeed they conjectured that for a general class of potentials of this type, quantum constants of higher order should
exist. We give credence to this conjecture by showing that for an even more general class of potentials in classicalmechanics,
there are higher-order constants of the motion as polynomials in the momenta. Thus these systems are all superintegrable. |
