Quantum averaging II: Kolmogorov's algorithm

Wolfgang Scherer

Published Apr 21, 1997• 24 citations

Abstract

A complete analogue of Kolmogorov's perturbation algorithm in classical mechanics is presented for perturbations of self-adjoint operators. The resulting perturbation theory is different from the usual Rayleigh - Schrödinger (or Kato - Rellich) perturbation theory.

Superconvergent Perturbation Method in Quantum Mechanics

Wolfgang Scherer

An analog of Kolmogorov's superconvergent perturbation theory in classical mechanics is constructed for self-adjoint operators. It is different from the usual Rayleigh-Schr\"odinger perturbation theory and yields expansions for eigenvalues and eigenvectors in terms of functions of the perturbation parameter.

Quantum averaging. I. Poincare-von Zeipel is Rayleigh Schrodinger

W Scherer

An exact analogue of the method of averaging in classical mechanics is constructed for self-adjoint operators. It is shown to be completely equivalent to the usual Rayleigh Schrodinger perturbation theory but gives the sums over intermediate states in closed-form expressions. The anharmonic oscillator and the Henon-Heiles system are treated as examples to illustrate the quantum averaging method.

Canonical averaging of the equations of quantum mechanics

A. G. Chirkov

The representation of a Schrodinger equations as a classic Hamiltonian system allows to construct a unified perturbation theory both in classic, and in a quantum mechanics grounded on the theory of canonical transformations, and also to receive asymptotic estimations of affinity of the precisian approximated solutions of Schrodinger equations

Iterative perturbation theory

Keith Hannabuss

Abstract The Rayleigh-Schrodinger theory described in the preceding chapter is by no means the only approach to stationary perturbation theory, nor is it usually the most powerful. As one of many possible alternatives we shall now describe an iterative procedure for approximating stationary states, sometimes called Wigner-Brillouin perturbation theory, which resembles the Feynman-Dyson method of Section 11.3.

A simple derivation of the series in perturbation theory

Luis Laín, Alicia Torre

A simple algorithm to derive the Brillouin-Wigner and the Rayleigh-Schrodinger series in time-independent perturbation theory is presented. The method provides a better understanding of the normalisation treatment of the perturbed wavefunctions and it establishes a clear relationship between the Brillouin-Wigner and Rayleigh-Schrodinger series.
