Controlling the RKKY interaction and heat transport in a Kitaev spin liquid via flux walls
Jun-Hui Zheng, Arne Brataas
Kitaev spin liquids (KSLs) contain both itinerant Majorana fermions and localized flux excitations. The mobile fermions transport energy, while the fluxes hinder heat flow. B…
Topological Mott transition in a Weyl-Hubbard model with dynamical mean-field theory
Bernhard Irsigler, Tobias Grass, Jun-Hui Zheng +2
Weyl semimetals are three-dimensional, topologically protected, gapless phases which show exotic phenomena such as Fermi arc surface states or negative magnetoresistance. It is an…
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…
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…
Topological invariant for two-dimensional open systems
Jun-Hui Zheng, Walter Hofstetter
We study the topology of two-dimensional open systems in terms of the Green's function. The Ishikawa-Matsuyama formula for the integer topological invariant is applied in open syst…
