Quantum materials, with nontrivial quantum phenomena and mechanisms, promise efficient
quantum technologies with enhanced functionalities. Quantum technology is held back …

Topological states of matter possess bulk electronic structures categorized by topological
invariants and edge/surface states due to the bulk-boundary correspondence. Topological …

Surface magnetism and its correlation with the electronic structure are critical to
understanding the topological surface state in the intrinsic magnetic topological insulator …

In three-dimensional (3D) crystals, emergent particles arise when two or multiple bands
contact and form degeneracy (band crossing) in the Brillouin zone. Recently a complete …

The study of topology in quantum materials has fundamentally advanced the understanding
in condensed matter physics and potential applications in next‐generation quantum …

The “hydrogen atom” of magnetic Weyl semimetals, with the minimum number of Weyl
points, has received growing attention recently due to the possible presence of Weyl-related …

Here we investigate antiferromagnetic Eu5In2Sb6, a nonsymmorphic Zintl phase. Our
electrical transport data show that Eu5In2Sb6 is remarkably insulating and exhibits an …

Recently, unconventional materials (or obstructed atomic insulators) have attracted much
attention owing to the unconventional feature of mismatch between Wannier centers and …

Nodal lines, as one-dimensional band degeneracies in momentum space, usually feature a
linear energy splitting. Here we propose the concept of magnetic higher-order nodal lines …

Kagome magnets provide a fascinating platform for a plethora of topological quantum
phenomena, in which the delicate interplay between frustrated crystal structure …
