Extensive v2DM study of the one-dimensional Hubbard model for large lattice sizes: Exploiting translational invariance and parity
Brecht Verstichel, Helen van Aggelen, Ward Poelmans +2
Using variational density matrix optimization with two- and three-index conditions we study the one-dimensional Hubbard model with periodic boundary conditions at various filling f…
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 determination of the second-order density matrix for the isoelectronic series of beryllium, neon and silicon
Brecht Verstichel, Helen van Aggelen, Dimitri Van Neck +2
The isoelectronic series of Be, Ne and Si are investigated using a variational determination of the second-order density matrix. A semidefinite program was developed that exploits…
