Query: Geminal-Based Configuration Interaction   The antisymmetrized geminal power (AGP) wave function has a long history and
considerable conceptual appeal, but in many situations its accuracy is wanting.
Here, we consider a form of configuration interaction (CI) based upon the AGP
wave function and taking advantage of its killing operators to construct an
excitation manifold. Our geminal CI reduces to standard
single-determinant--based CI in the limit in which AGP reduces to a single
determinant. It substantially improves upon AGP in the reduced BCS Hamiltonian,
which serves as a prototype for the kinds of strong pairing correlations
relevant in Bardeen-Cooper-Schrieffer--style superconductivity. Moreover, our
geminal CI naturally generalizes to add correlation to more general
geminal-based wave functions than AGP.
