Quasi exactly solvable (QES) equations with multiple algebraisations

Quantum Physics 2009-11-10 v1 High Energy Physics - Theory

Abstract

We review three examples of quasi exactly solvable (QES) Hamitonians which possess multiple algebraisations. This includes the most prominent example, the Lame equation, as well as recently studied many-body Hamiltonians with Weierstrass interaction potential and finally, a 2x2 coupled channel Hamiltonian.
