Quantum Geometry and Quantum Mechanics of Integrable Systems. II

Russian Journal of Mathematical Physics. 2010. Vol. 17. No. 2. P. 207-217.

For a generic quantum integrable system, we describe the asymptotics of the eigenstate density and of the trace of the evolution operator in all orders of the quantization parameter. This is done by using quantum symplectic geometry, which makes the given quantum system to be equivalent to a deformed classical system with arbitrary accuracy with respect to the quantization parameter. The asymptotics is explicitly given via the deformed symplectic form, deformed Liouville–Arnold tori, and deformed Maslov class.
