Investigations of random pair densities and the application to the N-representability problem

Pistol, Mats-Erik LU (2007) In Chemical Physics Letters 449(1-3). p.208-211
Abstract
We show that random pair densities that can arise from a many-body wavefunction have a distinct distribution of their eigenvalues, when interpreted as a kernel of an integral operator. This gives a probabilistic condition for pair densities as well as two-particle density matrices to be obtainable from a wavefunction. The condition depends on the number of particles in the system.
