Directhyphen;Product Representation of Wavefunctions

摘要

A directhyphen;product representation forNparticle wavefunctions is introduced through a coefficient matrixCp.Density matrices and the naturalpstates are redefined in terms ofCp.The projectionhyphen;operator formalism is used to derive an eigenvalue equation for the naturalpstates. A generalization of the exact selfhyphen;consistent field equations is derived from the concept of natural group functions.
