Symmetry enforced quantum spin Hall effect in Altermagnets
Fanzheng Chen, Lixin Zhang, Shuaishuai Niu +3
The quantum spin Hall effect (QSHE) has attracted widespread attention due to its dissipationless transport, which is protected by non-trivial topological invariants and helical ed…
Optically Driven Orbital Hall Transport in Floquet Odd-Parity Collinear Altermagnets with High Chern Numbers
Yuping Tian, Chen-Hao Zhao, Chao-Bo Wang +3
Recent studies have attracted increasing interest in nonrelativistic odd-parity magnetism and its associated topology in collinear altermagnets. Here, based on symmetry analysis an…
Interplay of Kekulé bond order and lattice instability in
Yuanhao Zhang, Zi Yuan, Xiangru Kong +2
Understanding the interplay between charge order and lattice instability in quantum materials remains a central challenge, as their coexistence often obscures causal relationships.…
Strain-engineering spin-valley locking effect in altermagnetic monolayer with multipiezo properties
Yuqian Jiang, Xinge Zhang, Haoyue Bai +3
Recently, altermagnetism (AM) in condensed matter systems has attracted much attention due to the physical properties arising from the alternating spins in both real space and reci…
