#### Abstract

Variational determination the ground state of two-particle Hamiltonian using the second-order reduced density matrix is very hopeful approach to quantum chemistry and condensed matter physics (J.Chem.Phys 114, 8282-8292 (2001)). The Quantum Marginal problem in this context is known as N-representability problem. If we employ some non-negativity conditions, which are necessary conditions of N-representability, the ground state energies are quite accurately calculated. In this talk, we show some results, and state some open questions to community.
