A natural orbital method for the electron momentum distribution in matter
arXiv:cond-mat/9804145 · doi:10.1016/S0022-3697(99)00313-3
Abstract
A variational method for many electron system is applied to momentum distribution calculations. The method uses a generating two-electron geminal and the amplitudes of the occupancies of one particle natural orbitals as variational parameters. It introduces correlation effects beyond the free fermion nodal structure.
