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 …

We review recent progress in the electronic structure study of intrinsic magnetic topological
insulators (MnBi2Te4)·(Bi2Te3) n () family. Specifically, we focus on the ubiquitously (nearly) …

Many experiments observed a metallic behavior at zero magnetic fields (antiferromagnetic
phase, AFM) in MnBi 2 Te 4 thin film transport, which coincides with gapless surface states …

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 …

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

The topological electronic structure plays a central role in the nontrivial physical properties
in topological quantum materials. A minimal,“hydrogen-atom-like” topological electronic …

Magnetism in topological materials creates phases exhibiting quantized transport
phenomena with potential technological applications. The emergence of such phases relies …

We have analyzed different factors responsible for changes in the Dirac gap in MnBi 2 Te 4
and the routes that determine the possibilities of the purposeful gap modulation. It was …

Isolated flat bands with significantly quenched kinetic energy of electrons could give rise to
exotic strongly correlated states from electron-electron interactions. More intriguingly, the …

Motivated by the recent experimental realization of the half-quantized Hall effect phase in a
three-dimensional (3D) semimagnetic topological insulator [M. Mogi, Nat. Phys. 18, 390 …
