Topological phases in the Fermi-Hofstadter-Hubbard model on hybrid-space ladders

Year: 2020

Type: article

Abstract: The Harper-Hofstadter model for spinful fermions at two-thirds filling is studied using a hybrid-space DMRG approach. Hall conductivity is computed and topological phases, including the appearance of a ferromagnetic ground state between the strongly interacting 1D and 2D models, are identified.
