A primal-dual semidefinite programming algorithm tailored to the variational determination of the two-body density matrix
B. Verstichel, H. van Aggelen, D. Van Neck +2
The quantum many-body problem can be rephrased as a variational determination of the two-body reduced density matrix, subject to a set of N-representability constraints. The mathem…

Variational density matrix optimization using semidefinite programming
Brecht Verstichel, Helen van Aggelen, Dimitri Van Neck +2
We discuss how semidefinite programming can be used to determine the second-order density matrix directly through a variational optimization. We show how the problem of characteriz…
