The density matrix renormalization group algorithm on kilo-processor architectures: implementation and trade-offs
Csaba Nemes, Gergely Barcza, Zoltán Nagy +2
In the numerical analysis of strongly correlated quantum lattice models one of the leading algorithms developed to balance the size of the effective Hilbert space and the accuracy…
Excited states in poly-diacetylene chains: A Density-matrix-renormalization-group study
Gergely Barcza, William Barford, Florian Gebhard +1
We study theoretically poly-diacetylene chains diluted in their monomer matrix. We employ the density-matrix renormalization group method (DMRG) on finite chains to calculate the g…
Orbital entanglement in bond-formation processes
Katharina Boguslawski, Pawel Tecmer, Gergely Barcza +2
The accurate calculation of the (differential) correlation energy is central to the quantum chemical description of bond-formation and bond-dissociation processes. In order to esti…
