Many-body experts like to start from the one-particle approximation. Even when geminals or group functions are used they are ultimately expanded in the one-particle basis (Wilson 1984).

Notwithstanding their hopes the majority votes for one-particle approximation, because it is fundamental to our intuitions and capable of high accuracy (cf Handy 1978).
