Direct observation of anisotropic exciton dispersion in the 2D semiconductor CrSBr
Yiwen Song, Peiyi He, Weizhe Zhang +7
The authors use momentum‑resolved electron energy‑loss spectroscopy and first‑principles calculations to measure exciton dispersion in multilayer CrSBr, revealing a strong in‑plane…

Emergent Atomic Scale Polarisation Vortices in BaTiS3
Boyang Zhao, Gwan Yeong Jung, Shantanu Singh +21
Topological defects, such as vortices and skyrmions in magnetic and dipolar systems, can give rise to properties that are not observed in typical magnets and dielectrics. Here, we…

Intertwined polar, chiral, and ferro-rotational orders in a rotation-only insulator
Weizhe Zhang, June Ho Yeo, Xiaoyu Guo +8
Intertwined orders refer to strongly coupled and mutually dependent orders that coexist in correlated electron systems, often underpinning key physical properties of the host mater…
