Screening in Hubbard models with long-range interactions
Florian Gebhard, Kevin Bauerbach, Ãrs 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…

Loss-induced quantum information jet in an infinite temperature Hubbard chain
Patrik Penc, CÄtÄlin PaÅcu Moca, Ãrs Legeza +3
Information propagation in the one-dimensional infinite temperature Hubbard model with a dissipative particle sink at the end of a semi-infinite chain is studied. In the strongly i…
