Specifically, working with the algebro-geometric definition of quantum integrability, we utilize the bispectral duality of quantum Hamiltonian systems to construct non-trivial Darboux transformations between completely integrable quantum systems. As an application, we are able to construct new quantum integrable systems as the Darboux transforms of trivial examples (such as symmetric products of one dimensional systems) or by Darboux transformation of well-known bispectral systems such as quantum Calogero-Moser.10 pages, no figuresMathematical PhysicsCommutative AlgebraExactly Solvable and Integrable SystemsQuantum Physics81S05 13N10 58G37 58F07 47F05 32C38text
