Quartic Poisson algebras and quartic associative algebras and realizations as deformed oscillator algebras
Ian Marquette
We introduce the most general quartic Poisson algebra generated by a second and a fourth order integral of motion of a 2D superintegrable classical system. We obtain the correspond…

New ladder operators for a rational extension of the harmonic oscillator and superintegrability of some two-dimensional systems
I. Marquette, C. Quesne
New ladder operators are constructed for a rational extension of the harmonic oscillator associated with type III Hermite exceptional orthogonal polynomials and characterized by an…
