Fractional Chern insulators (FCIs) are lattice generalizations of the conventional fractional
quantum Hall effect (FQHE) in two-dimensional (2D) electron gases. They typically arise in a …

Quantum Hall effects with multicomponent internal degrees of freedom facilitate the
playground of novel emergent topological orders. Here, we explore the correlated …

We propose an all-optical scheme of topological lasing and switching based on the Aubry-
André-Harper (AAH) model of an exciton-polariton chain. We theoretically show that the …

We study the many-body ground states of three-component quantum particles in two
prototypical topological lattice models under strong intercomponent and intracomponent …

The Halperin (m′, m, n) fractional quantum Hall effects of two-component quantum particles
are studied in topological checkerboard lattice models. Here for m≠ m′, we demonstrate …

We study the many-body ground states of two-component hard-core bosons in topological
triangular-lattice models. Utilizing exact diagonalization and density-matrix renormalization …
