Efficient adiabatic connection approach for strongly correlated systems. Application to singlet-triplet gaps of biradicals
Daria Drwal, Pavel Beran, Michał Hapka +4
Strong correlation can be essentially captured with multireference wavefunction methods such as complete active space self-consistent field (CASSCF) or density matrix renormalizati…

Density matrix renormalization group with dynamical correlation via adiabatic connection
Pavel Beran, Mikuláš Matoušek, Michał Hapka +2
The quantum chemical version of the density matrix renormalization group (DMRG) method has established itself as one of the methods of choice for calculations of strongly correlate…
