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

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Axion, first postulated as a hypothetical particle in high-energy physics, is now extended to
describe a novel topological magnetoelectric effect derived from the Chern–Simons theory …

Topological materials, which feature robust surface and/or edge states, have now been a
research focus in condensed matter physics. They represent a new class of materials …

The layer Hall effect describes electrons spontaneously deflected to opposite sides at
different layers, which has been experimentally reported in the MnBi2Te4 thinfilms under …

Recently, a type of Hall effect due to an unusual layer-locked Berry curvature called the layer
Hall effect (LHE) has been reported in the even-layered two-dimensional antiferromagnetic …

Being the first intrinsic antiferromagnetic (AFM) topological insulator (TI), MnBi2Te4 is
argued to be a topological axion state in its even-layer form due to the antiparallel …

Surface electrons in axion insulators are endowed with a topological layer degree of
freedom followed by exotic transport phenomena, eg, the layer Hall effect. Here, we propose …

Transitions between distinct obstructed atomic insulators (OAIs) protected by crystalline
symmetries, where electrons form molecular orbitals centering away from the atom positions …

We propose an intrinsic mechanism to understand the even-odd effect, namely, opposite
signs of anomalous Hall resistance and different shapes of hysteresis loops for even and …
