Integrability and action operators in quantum Hamiltonian systems

Vyacheslav V. Stepanov, Gerhard Muller

For a (classically) integrable quantum mechanical system with two degrees of freedom, the functional dependence $H^= H_{Q} (J^_{1}, J^_{2})$ of the Hamiltonian operator on th…

Signatures of quantum integrability and nonintegrability in the spectral properties of finite Hamiltonian matrices

Vyacheslav V. Stepanov, Gerhard Muller

For a two-spin model which is (classically) integrable on a five-dimensional hypersurface in six-dimensional parameter space and for which level degeneracies occur exclusively (wit…
