Non-Abelian Fractional Chern Insulators from Long-Range Interactions
Zhao Liu, Emil J. Bergholtz, Eliot Kapit
The recent theoretical discovery of fractional Chern insulators (FCIs) has provided an important new way to realize topologically ordered states in lattice models. In earlier works…
Topological Flat Band Models and Fractional Chern Insulators
Emil J. Bergholtz, Zhao Liu
Topological insulators and their intriguing edge states can be understood in a single-particle picture and can as such be exhaustively classified. Interactions significantly compli…
Tunable Band Topology Reflected by Fractional Quantum Hall States in Two-Dimensional Lattices
Dong Wang, Zhao Liu, Junpeng Cao +1
Two-dimensional lattice models subjected to an external effective magnetic field can form nontrivial band topologies characterized by nonzero integer band Chern numbers. In this Le…
Bulk-edge correspondence in fractional Chern insulators
Zhao Liu, D. L. Kovrizhin, Emil J. Bergholtz
It has been recently realized that strong interactions in topological Bloch bands give rise to the appearance of novel states of matter. Here we study connections between these sys…
