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…
