Tensor Networks -QC-DMRG- in a Complete Active Space Coupled Cluster Method

Explore tensor networks and their application in quantum mechanics through this lecture on "Tensor Networks (QC-DMRG) in a Complete Active Space Coupled Cluster Method." Delve into the formulation of the Schrödinger equation using tree-based tensor networks in discrete Fock space, and learn about solving techniques like DMRG. Discover how combining MPS-DMRG with MR-SCF-CAS and tailored multi-reference coupled cluster methods can effectively handle both strong correlation phenomena and dynamical correlations. Gain insights into convergence analysis, cost considerations, and the ability to compute degenerate and nearly degenerate states. Cover topics such as coupled cluster theory, intermediate normalization, tensor networks, DMRG, and multireference coupled cluster equations throughout this comprehensive presentation by Reinhold Schneider from Technische Universität Berlin.
