Asymptotics of the Spectrum and Quantum Averages near the Boundaries of Spectral Clusters for Perturbed Two-Dimensional Oscillators
A. V. Pereskokov Moscow Power Engineering Institute (Technical University)
Abstract:
The eigenvalue problem for the perturbed resonant oscillator is considered. A method for constructing asymptotic solutions near the boundaries of spectral clusters using a new integral representation is proposed. The problem of calculating the averaged values of differential operators on solutions near the cluster boundaries is studied.
Keywords:
spectral cluster, resonance, operator averaging method, coherent transform, WKB-approximation, turning point.
