WebHence, a common alternative to Slater determinants are configuration state functions (CSFs), which are simply linear combinations of Slater determinants chosen to be eigenfunctions of S ^ 2. The benefit of using CSFs over determinants is that fewer N -electron functions are needed to describe the same state.

So, in a single-determinant limit, the electrons are still \uncorrlated"(In the sense of independent product distributions.)

In quantum mechanics, a Slater determinant is an expression that describes the wave function of a multi-fermionic system. It satisfies anti-symmetry requirements, and consequently the Pauli principle, by changing sign upon exchange of two electrons (or other fermions). Only a small subset of all possible fermionic wave functions can be written as a single Slater determinant, but those form an important and useful subset because of their simplicity.
