Altermagnetism produces pair emission and absorption from dark excitons and magnons in LaOMnSe
Birender Singh, Xian Xu, Sabrina R. Hatt +21
Altermagnets' (AMs) non-relativistic spin splitting enables novel states, spintronic and magneto-optical devices, though their optical signatures remain elusive. Here, we report ex…
Spin-chirality-driven nonrelativistic Edelstein effects in two-dimensional antiferromagnets
Hao Zuo, Xiaoyin Li, Jian Zhou
Charge current-induced magnetic moment accumulation-Edelstein effect has been extensively attracting attention for its promising applications in spintronics. While most prior works…
Symmetry-Protected Weyl Nodal Loops in a Triangular Altermagnet
Chao-Chun Wei, Xiaoyin Li, Sophia Adams +9
Weyl semimetals and altermagnets represent two distinct classes of quantum materials exhibiting nontrivial topological and magnetic order, respectively. Here we report the realizat…
Interplay of Quantum Size Effect and Tensile Strain on Surface Morphology of Sn(100) Islands
Bing Xia, Xiaoyin Li, Hongyuan Chen +16
The quantum size effect (QSE) and strain effect are two key factors influencing the surface morphology of thin films, which can increase film surface roughness through QSE-induced…
LaOMnSe: a correlated insulating layered d-wave altermagnet
Chao-Chun Wei, Xiaoyin Li, Sabrina Hatt +12
Altermagnets represent a new class of magnetic phases without net magnetization that are invariant under a combination of rotation and time reversal. Unlike conventional collinear…
Graph Theorem for Chiral Exact Flat Bands at Charge Neutrality
Gurjyot Sethi, Bowen Xia, Dongwook Kim +3
Chiral exact flat bands (FBs) at charge neutrality have attracted much recent interest, presenting an intriguing condensed-matter system to realize exact many-body phenomena, as sp…
