Numerical Constructions of Perturbation Series in Quantum Mechanics
arXiv:quant-ph/0008116
Abstract
A few modified textbook Rayleigh-Schrödinger perturbative representations of bound states are reviewed. They were all inspired by an adaptive re-split of the Hamiltonian, using nonstandard bases and the flexibility of normalization of the wave functions.
