A nonorthogonal state-interaction approach for matrix product state wave functions
Stefan Knecht, Sebastian Keller, Jochen Autschbach +1
We present a state-interaction approach for matrix product state (MPS) wave functions in a nonorthogonal molecular orbital basis. Our approach allows us to calculate for example tr…
Multi-reference perturbation theory with Cholesky decomposition for the density matrix renormalization group
Leon Freitag, Stefan Knecht, Celestino Angeli +1
We present a second-order N-electron valence state perturbation theory (NEVPT2) based on a density matrix renormalization group (DMRG) reference wave function that exploits a Chole…
Self-Consistent Embedding of Density-Matrix Renormalization Group Wavefunctions in a Density Functional Environment
Thomas Dresselhaus, Johannes Neugebauer, Stefan Knecht +3
We present the first implementation of a density matrix renormalization group algorithm embedded in an environment described by density functional theory. The frozen density embedd…
