The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Magnetic topological insulators (MTIs) offer a combination of topologically nontrivial
characteristics and magnetic order and show promise in terms of potentially interesting …

A quantum anomalous Hall (QAH) state is a two-dimensional topological insulating state that
has a quantized Hall resistance of h/(Ce 2) and vanishing longitudinal resistance under zero …

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

We demonstrate the anomalous Hall effect (AHE) in single-layer graphene exchange
coupled to an atomically flat yttrium iron garnet (YIG) ferromagnetic thin film. The anomalous …

The intense theoretical and experimental interest in topological insulators and semimetals
has established band structure topology as a fundamental material property. Consequently …

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 investigate the quantum anomalous Hall effect (QAHE) and related chiral transport in the
millimeter-size (Cr 0.12 Bi 0.26 Sb 0.62) 2 Te 3 films. With high sample quality and robust …
