Physical Review A

Perturbation theory for Heisenberg operators

Francisco Marcelo Fernández

Published Feb 10, 2003• 3 citations

Abstract

We compare a recently proposed perturbation method for quantum-mechanical observables with the well-known standard perturbation approach and the Magnus expansion.Received 14 August 2002DOI:https://doi.org/10.1103/PhysRevA.67.022104©2003 American Physical Society
