Second-order topology in two-dimensional azulenoid kekulene carbon lattices
Xiaorong Zou, Hyeon Suk Shin, Chang-Jong Kang +5
The discovery of higher-order topological insulator (HOTI) has established a new paradigm for understanding symmetry-constrained boundary electronic states. Here, based on first-pr…
Magnonic Quantum Spin Hall Effect with Chiral Magnon Transport in Bilayer Altermagnets
Bo Yuan, Yingxi Bai, Ying Dai +2
Altermagnetism has attracted considerable interest, yet its associated spintronic phenomena have so far been largely confined to electronic systems. In this work, we uncover a univ…
Coexistence and tunability of orbital and spin Hall effects in RuO
Lishu Zhang, Mahmoud Zeer, Dongwook Go +8
Altermagnetic materials, especially RuO, have recently attracted considerable attention for their unique magnetic properties and energy-efficient spintronic applications. Howev…
Topology-engineered orbital Hall effect in two-dimensional ferromagnets
Zhiqi Chen, Runhan Li, Yingxi Bai +7
Recent advances in manipulation of orbital angular momentum (OAM) within the paradigm of orbitronics present a promising avenue for the design of future electronic devices. In this…
Hidden wallpaper fermion and third-order topological insulator
Ning Mao, Hao Wang, Ying Dai +2
Nonsymmorphic symmetry can induce exotic wallpaper fermions, e.g., hourglass fermion, fourfold-degenerate Dirac fermion, and Möbius fermion, as commonly believed only in nonsymmorp…
Quantum spin Hall effect and topological phase transitions in honeycomb antiferromagnets
C. Niu, J. -P. Hanke, P. M. Buhl +4
While the quantum spin Hall (QSH) effect and antiferromagnetic order constitute two of the most promising phenomena for embedding basic spintronic concepts into future technologies…
