Correlation energy of a model problem

A newly derived generalized moments expansion (GMX), based on the “ t-expansion” of Horn and Weinstein, is used to calculate the correlation energy of a model Hamiltonian representing N coupled one-dimensional harmonic oscillators. Comparisons are made with a related calculational scheme the canonic...

Description
Summary:A newly derived generalized moments expansion (GMX), based on the “ t-expansion” of Horn and Weinstein, is used to calculate the correlation energy of a model Hamiltonian representing N coupled one-dimensional harmonic oscillators. Comparisons are made with a related calculational scheme the canonical sequence method (CSM).
