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…
Entanglement and chaos in warped conformal field theories
Luis Apolo, Song He, Wei Song +2
Various aspects of warped conformal field theories (WCFTs) are studied including entanglement entropy on excited states, the Renyi entropy after a local quench, and out-of-time-ord…
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…
Interaction-enhanced integer quantum Hall effect in disordered systems
Jun-Hui Zheng, Tao Qin, Walter Hofstetter
We study transport properties and topological phase transition in two-dimensional interacting disordered systems. Within dynamical mean-field theory, we derive the Hall conductance…
