A Conjecture on Antisymmetrized Geminal Power Wavefunctions
Patrick Cassam-Chenaï
We conjecture that ``Antisymmetrized Geminal Power'' wave functions, and, in particular, those of extreme type in Coleman's terminology (i.e. with all geminal coefficients equal),…

Improving Guess Geminals for the Geminal Mean Field Configuration Interaction Method
Patrick Cassam-Chenaï, Giovanni Granucci
The purpose of this letter is to show that a rotation of Hartree-Fock canonical orbitals which minimizes the lowest eigenvalues of a configuration interaction calculation limited t…

Geometric Measure of Indistinguishability for Groups of Identical Particles
Patrick Cassam-Chenaï
The concept of p-orthogonality (1=< p =< n) between n-particle states is introduced. It generalizes common orthogonality, which is equivalent to n-orthogonality, and strong orthogo…
