Abstract
An attempt is made in this work to extend the correlated variational approach of Chen and Mei [1], which was developed for two-electron systems, to N-electron systems (N>2). Preliminary results are reported here for four electrons interacting under a Hubbard-type potential in a one-dimensional lattice with only four sitesJournal of the Nigerian Association of Mathematical Physics Vol. 8 2004: pp. 337-340
