Investigations of random pair densities and the application to the N-representability problem
Research output: Contribution to journal › Article
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.
