Spin contamination and noncollinearity in general complex Hartree-Fock wave functions
Patrick Cassam-Chenaï
An expression for the square of the spin operator expectation value, \textless{} S^2\textgreater{}, is obtained for a general complex Hartree-Fock (GCHF) wave function and decompos…

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…
