The concept of topological energy bands and their manifestations have been demonstrated
in condensed matter systems as a fantastic paradigm toward unprecedented physical …

Topological phases with insulating bulk and gapless surface or edge modes have attracted
intensive attention because of their fundamental physics implications and potential …

Photonic crystals offer unprecedented opportunity for light manipulation and applications in
optical communication and sensing,,,. Exploration of topology in photonic crystals and …

The extensive research of two-dimensional layered materials has revealed that valleys, as
energy extrema in momentum space, could offer a new degree of freedom for carrying …

This article reviews the theoretical and experimental work related to the electronic properties
of bilayer graphene systems. Three types of bilayer stackings are discussed: the AA, AB, and …

Over a long period of exploration, the successful observation of quantized version of
anomalous Hall effect (AHE) in thin film of magnetically doped topological insulator (TI) …

We review the electronic properties of bilayer graphene, beginning with a description of the
tight-binding model of bilayer graphene and the derivation of the effective Hamiltonian …

We theoretically demonstrate that the second-order topological insulator with robust corner
states can be realized in two-dimensional Z 2 topological insulators by applying an in-plane …

We find theoretically a new quantum state of matter—the valley-polarized quantum
anomalous Hall state in silicene. In the presence of Rashba spin-orbit coupling and an …

Topological insulators are a recently discovered class of materials having insulating bulk
electronic states but conducting boundary states distinguished by nontrivial topology. So far …
