Testing one-body density functionals on a solvable model [PDF]
Carlos L. Benavides-Riveros, Joseph C. VárillyThere are several physically motivated density matrix functionals in the literature, built from the knowledge of the natural orbitals and the occupation numbers of the one-body reduced density matrix. With the help of the equivalent phase-space formalism, we thoroughly test some of the most popular of those functionals on a completely solvable model.View original: http://arxiv.org/abs/1207.3897
