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…
The half-life of Fr in Si and Au at 4K and at mK temperatures
F. Wauters, B. Verstichel, M. Breitenfeldt +10
The half-life of the decaying nucleus Fr was determined in different environments, i.e. embedded in Si at 4 K, and embedded in Au at 4 K and about 20 mK. No differences…
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…
