A quantum informational approach for dissecting chemical reactions
Corinne Duperrouzel, Paweł Tecmer, Katharina Boguslawski +3
We present a conceptionally different approach to dissect bond-formation processes in metal-driven catalysis using concepts from quantum information theory. Our method uses the ent…
Phase Separation of Superfluids in the Chain of Four-Component Ultracold Atoms
G. Barcza, E. Szirmai, J. Sólyom +1
We investigate the competition of various exotic superfluid states in a chain of spin-polarized ultracold fermionic atoms with hyperfine spin and s-wave contact interacti…
Investigation of metal-insulator like transition through the ab initio density matrix renormalization group approach
E. Fertitta, B. Paulus, G. Barcza +1
We have studied the Metal-Insulator like Transition (MIT) in lithium and beryllium ring-shaped clusters through ab initio Density Matrix Renormalization Group (DMRG) method. Perfor…
Entanglement patterns and generalized correlation functions in quantum many body systems
G. Barcza, R. M. Noack, J. Sólyom +1
We introduce transition operators that in a given basis of the single-site states of a many-body system have a single non-vanishing matrix element and introduce their correlation f…
Interorbital interaction in the one-dimensional periodic Anderson model: A density-matrix renormalization-group study
I. Hagymasi, J. Solyom, O. Legeza
We investigate the effect of the Coulomb interaction, , between the conduction and f electrons in the periodic Anderson model using the density-matrix renormalization-group…
Quantum Entanglement in Carbon-Carbon, Carbon-Phosphorus and Silicon-Silicon Bonds
Matthieu Mottet, Pawel Tecmer, Katharina Boguslawski +2
The chemical bond is an important local concept to understand chemical compounds and processes. Unfortunately, like most local concepts, the chemical bond and the bond order do not…
