Strongly Correlated Electrons

Abstract
We present an efficient approach to the electron correlation problem that is well-suited for strongly interacting many-body systems, but requires only mean-field-like computational cost. %which is based on orbital optimization of electron pairs. The performance of our approach is illustrated for the one-dimensional Hubbard model with periodic boundary conditions for different chain lengths, and for the non-relativistic quantum chemical Hamiltonian exploring the symmetric dissociation of the H hydrogen chain.
