Screening in Hubbard models with long-range interactions
Florian Gebhard, Kevin Bauerbach, Örs Legeza
We provide solid evidence for the long-standing presumption that model Hamiltonians with short-range interactions faithfully reproduce the physics of the long-range Coulomb interac…
Topologically protected, correlated end spin formation in carbon nanotubes
Cătălin Paşcu Moca, Wataru Izumida, Balázs Dóra +3
For most chiralities, semiconducting nanotubes display topologically protected end states of multiple degeneracies. We demonstrate using density matrix renormalization group based…
Manual for the Flexible DM-NRG code
O. Legeza, C. P. Moca, A. I. Toth +2
Quantum impurity models describe interactions between some local degrees of freedom and a continuum of non-interacting fermionic or bosonic states. The investigation of quantum imp…
Density matrix numerical renormalization group for non-Abelian symmetries
A. I. Toth, C. P. Moca, O. Legeza +1
We generalize the spectral sum rule preserving density matrix numerical renormalization group (DM-NRG) method in such a way that it can make use of an arbitrary number of not neces…
