Interaction-driven topological phase transitions in fermionic SU() systems
Mohsen Hafez-Torbati, Jun-Hui Zheng, Bernhard Irsigler +1
We consider SU() fermions on the triangular lattice in the presence of a gauge potential which stabilizes a quantum Hall insulator (QHI) at the density of one particle per latti…
Z2 characterization for three-dimensional multiband Hubbard models
Bernhard Irsigler, Jun-Hui Zheng, Fabian Grusdt +1
We introduce three numerical methods for characterizing the topological phases of three-dimensional multiband Hubbard models based on twisted boundary conditions, Wilson loops, as…
Bulk topological proximity effect in multilayer systems
Jaromir Panas, Bernhard Irsigler, Jun-Hui Zheng +1
We investigate the bulk topological proximity effect in multilayer hexagonal lattice systems by which one can introduce topological properties into a system composed of multiple tr…
Microscopic characteristics and tomography scheme of the local Chern marker
Bernhard Irsigler, Jun-Hui Zheng, Walter Hofstetter
The concept of the local Chern marker has gained a lot of attention especially in the field of ultracold quantum gases in optical lattices and artificial gauge fields. We investiga…
