Optical phonons for Peierls chains with long-range Coulomb interactions
Máté Timár, Gergely Barcza, Florian Gebhard +1
We consider a chain of atoms that are bound together by a harmonic force. Spin-1/2 electrons that move between neighboring chain sites (Hückel model) induce a lattice dimerization…
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…
