Painlevé VI superintegrability and Heun-Racah algebras

Ian Marquette, Sarah Post

We study the two fourth-order quantum superintegrable systems in the Euclidean plane that separate in polar coordinates and whose angular potentials are determined by the general f…

Quasi-exactly solvable deformations of quantum systems associated with exceptional orthogonal polynomials

Siyu Li, Ian Marquette, Sarah Post +1

Quasi-exactly solvable (QES) deformations of harmonic and singular oscillators have been widely studied via a range of approaches. In this paper, we obtain families of new QES defo…
