Measuring the topological phase transition via the single-particle density matrix
Jun-Hui Zheng, Bernhard Irsigler, Lijia Jiang +2
We discuss the topological phase transition of the spin- fermionic Haldane model with repulsive on-site interaction. We show that the Berry curvature of the topologica…
Spin-imbalance-induced transverse magnetization in the Hofstadter-Hubbard model
Bernhard Irsigler, Jun-Hui Zheng, Mohsen Hafez-Torbati +1
The fermionic, time-reversal invariant Hofstadter-Hubbard model with a population difference between the two spin states is investigated. In the strongly interacting regime, where…
Interacting Hofstadter Interface
Bernhard Irsigler, Jun-Hui Zheng, Walter Hofstetter
Two-dimensional topological insulators possess conducting edge states at their boundary while being insulating in the bulk. The detection of edge states remains an open question in…
