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

Topological electronic materials, such as topological insulators, are distinct from trivial
materials in the topology of their electronic band structures that lead to robust …

The quantum anomalous Hall (QAH) effect combines topology and magnetism to produce
precisely quantized Hall resistance at zero magnetic field. We report the observation of a …

When two sheets of graphene are stacked at a small twist angle, the resulting flat
superlattice minibands are expected to strongly enhance electron-electron interactions …

The importance of global band topology is unequivocally recognized in condensed matter
physics, and new states of matter, such as topological insulators, have been discovered …

The intrinsic magnetic topological insulator MnBi 2 Te 4 exhibits rich topological effects such
as quantum anomalous Hall effect and axion electrodynamics. Here, by combining the use …

Electrons in moiré flat band systems can spontaneously break time-reversal symmetry,
giving rise to a quantized anomalous Hall effect. In this study, we use a superconducting …

Ferromagnetic topological insulators exhibit the quantum anomalous Hall effect, which is
potentially useful for high‐precision metrology, edge channel spintronics, and topological …

Weyl fermions were originally proposed as massless Dirac fermions in relativistic quantum
field theory. In solids, Weyl fermions often appear when either time-reversal symmetry or …

In general, inorganic non‐metallic materials exhibit brittleness, and achieving plasticity in
wide‐gap semiconductors or dielectrics poses an even greater challenge. Historically, silver …
