Integrable Quantum Systems  

In General > s.a. coherent states; integrable classical systems; non-commutative theories; special potentials [exactly solvable, etc].
* Idea: Quantum systems for which the energy spectrum can be explicitly computed.
* Energy eigenvalues: The energies of the tori whose actions in the semiclassical limit are of the form (n + k/8) h, with n arbitrary and k some fixed integer [KAM theory; & Einstein; Brillouin; Keller; Maslov].
