In the ground state the pair density n can be determined by solving a single auxiliary equation of a two-particle problem. Exact differential and integral constraints for the Pauli potential of the effective potential of the two-particle equation are presented. The constraints are derived using the differential virial theorem and the Hiller-Sucher-Feinberg identity.

Abstract
In the ground state the pair density n can be determined by solving a single auxiliary equation of a two-particle problem. Exact differential and integral constraints for the Pauli potential of the effective potential of the two-particle equation are presented. The constraints are derived using the differential virial theorem and the Hiller-Sucher-Feinberg identity.File in questo prodotto:
