Second-Order Self-Consistent-Field Density-Matrix Renormalization Group
Yingjin Ma, Stefan Knecht, Sebastian Keller +1
We present a matrix-product state (MPS)-based quadratically convergent density-matrix renormalization group self-consistent-field (DMRG-SCF) approach. Following a proposal by Werne…
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…
Spin-adapted Matrix Product States and Operators
Sebastian Keller, Markus Reiher
Matrix product states (MPSs) and matrix product operators (MPOs) allow an alternative formulation of the density matrix renormalization group algorithm introduced by White. Here, w…
