Floquet-Engineered Odd-Parity Altermagnetic Higher-Order Topology in a Two-Dimensional Antiferromagnet CrCH
Xiaorong Zou, Hyeon Suk Shin, Baibiao Huang +5
Periodic driving provides a platform to dynamically tailor quantum states of matter, yet its impact on symmetry-protected topological phases remains incompletely understood. Here,…
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…
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…
Pyrochlore NaYbO2: A potential Quantum Spin Liquid Candidate
Chuanyan Fan, Tieyan Chang, Longlong Fan +14
The search for quantum spin liquids (QSL) and chemical doping in such materials to explore superconductivity have continuously attracted intense interest. Here, we report the disco…
Detection and control of electronic orbital magnetism by spin waves in honeycomb ferromagnets
Lichuan Zhang, Lu Zhang, Dongwook Go +6
Exploring and manipulating the orbital degrees of freedom in solids has become a fascinating research topic in modern magnetism. Here, we demonstrate that spin waves can provide a…
