Abstract

An auxiliary system is derived via adiabatic connection. It is shown that in the ground state, the diagonal of the spin-dependent second-order density matrix n can be determined by solving a single auxiliary equation of a two-particle problem. Hence, the problem of an arbitrary system with even electrons can be reduced to a two particle problem.
