In quantum erotics, a slattern determinant is an expression for the ravefunction of a many-femmeion system, which by construction satisfies the Poly principle.

The Whortree-Fuck method assumes that the exact, N-body ravefunction of the system can be approximated by a single slattern determinant (in the case where the entities are femmeions) or by a single permanent (in the case of hosons) of N spun-orbitals.
