The reduced-density-matrix method is an promising candidate for the next generation electronic structure calculation method; it is equivalent to solve the Schr\"odinger equation for the ground state. The number of variables is the same as a four electron system and constant regardless of the electrons in the system. Thus many researchers have been dreaming of a much simpler method for quantum mechanics. In this chapter, we give a overview of the reduced-density matrix method; details of the…

The electronic ground-state energy problem: a new reduced density matrix approach.

It is shown that the computation of the ground-state energy reduces to the search of the projection of some two-electron reduced Hamiltonian on the dual cone of N-representability conditions.

The reduced density matrix method for electronic structure calculations and the role of three-index representability conditions.

The variational approach for electronic structure based on the two-body reduced density matrix is studied, incorporating two representability conditions beyond the previously used P, Q, and G conditions, and it is found that the use of the T1 and T2 conditions gives a significant improvement over just the P,Q, andG conditions.

An efficient algorithm with an order-of-magnitude reduction in floating-point operations and memory usage is presented and automatically treats strong, multireference correlation when the optimization occurs on the space of two electrons.

Variational calculation of second-order reduced density matrices by strong N-representability conditions and an accurate semidefinite programming solver.

This work explores the well-known N-representability conditions (P, Q, and G) together with the more recent and much stronger T1 and T2(') conditions and provides physically meaningful results for the Hubbard model in the high correlation limit.
