Adiabatic Theorem Violation for Degenerate Energy Levels

Physica Scripta, 1999
For the exactly solvable model of a two-mode oscillator with slowly varying frequency of one of the modes it is demonstrated that such a quantum number as the angular momentum of the oscillator is not conserved in the adiabatic limit.

Sensitivity at the degenerate points of energy levels in a quantum system with nonintegrable perturbation

Physical Review E, 2001
The behavior of quantum states and observables of a quasi-integrable quantum system is studied. Sensitivity of the quantum states and nonperiodicity of the average value of observables at the degenerate points of energy levels are observed. The behavior demonstrates the quantum properties corresponding to the classical resonant tori with rational ...

Diagrammatic analysis of adiabatic and time-independent perturbation theory for degenerate energy levels

Chemical Physics Letters, 1978
Time-ordered folded diagrams are used to represent the effective hamiltonian in the adiabatic formalism. Resummation of the diagrams is shown to give a term-by-term correspondence with time-independent perturbation ...
