Three-dimensional (3D) topological semimetals represent a new class of topological
matters. The study of this family of materials has been at the frontiers of condensed matter …

The discovery of the quantum Hall effect (QHE), in two-dimensional electronic systems has
given topology a central role in condensed matter physics. Although the possibility of …

Magneto‐optic effect is attracting wide interest as it renders a contactless, potentially power‐
free, highly sensitive and spatio‐temporal resolved way in both magnetic material …

Discovered decades ago, the quantum Hall effect remains one of the most studied
phenomena in condensed matter physics and is relevant for research areas such as …

In topological semimetals, the valance band and conduction band meet at zero-dimensional
nodal points or one-dimensional nodal rings, which are protected by band topology and …

Abstract 2D layered materials have emerged in recent years as a new platform to host novel
electronic, optical, or excitonic physics and develop unprecedented nanoelectronic and …

Topological nodal-line semimetals are characterized by one-dimensional lines of band
crossing in the Brillouin zone. In contrast to nodal points, nodal lines can be in topologically …

The nonlinear Hall effect due to Berry curvature dipole (BCD) induces frequency doubling,
which was recently observed in time-reversal-invariant materials. Here we report novel …

A quantum spin Hall (QSH) insulator hosts topological states at the one-dimensional (1D)
edge, along which backscattering by nonmagnetic impurities is strictly prohibited. Its 3D …

Topological semimetals represent a new class of quantum materials hosting Dirac/Weyl
fermions. The essential properties of topological fermions can be revealed by quantum …
