DOI: 10.1038/s41467-025-59160-z
Abstract: The Dissipationless chiral edge state (CES) stands as a pivotal feature in quantum anomalous Hall (QAH) insulators. The dissipationless nature and chirality give rise to unique transport properties and provide insights into future electronics and… read more here.

DOI: 10.1103/physrevb.100.174414
Abstract: We show that ac driven skyrmion lattices in a weak pinning channel confined by regions of strong pinning exhibit edge transport carried by skipping orbits while skyrmions in the bulk of the channel undergo localized… read more here.

Abstract: We present a scheme of interaction-induced topological band structures based on the spin anisotropy of exciton-polaritons in semiconductor microcavities. We predict theoretically that this scheme allows the engineering of topological gaps, without requiring a magnetic… read more here.

Abstract: The relation between chiral edge modes and bulk Chern numbers of quantum Hall insulators is a paradigmatic example of bulk-boundary correspondence. We show that the chiral edge modes are not strictly tied to the Chern… read more here.

DOI: 10.1103/physrevlett.130.086201
Abstract: In quantum anomalous Hall (QAH) insulators, the interior is insulating but electrons can travel with zero resistance along one-dimensional (1D) conducting paths known as chiral edge channels (CECs). These CECs have been predicted to be… read more here.

DOI: 10.1103/physrevlett.132.156602
Abstract: Photonic Chern insulators are known for their topological chiral edge states (CESs), whose absolute existence is determined by the bulk band topology, but concrete dispersion can be engineered to exhibit various properties. For example, the… read more here.

DOI: 10.1364/ol.462005
Abstract: Chiral edge states (CESs) have been demonstrated at the external boundary of a valley photonic crystal (VPC), with flexibly tunable group velocity and frequency range by adjusting the boundary structure. In this work, we show… read more here.
