Group theory of Raman effect in magnetic materials
Rui-Chun Xiao, Xue Liu, Yuxuan Jiang +5
Despite the wealth of experimental observations on Raman scattering in magnetic materials, the underlying selection rules have remained largely unexplored. In this work, we use Ons…
Elastoresistivity Signatures of Nematic Fluctuations in Layered Antiferromagnet CoTa3S6
Tao Lu, Zili Feng, Mengxing Ye +2
Nematic phases that break rotational symmetry are widely observed in quantum materials, and clarifying their origin and relationship with other symmetry-breaking phases remains an…
Tunable decoupling of coexisting magnetic orders in CoTaS
Yining Hu, Zili Feng, Takashi Kurumaji +3
In multiferroics, new physical responses and functionalities emerge when symmetry-distinct order parameters couple. This conventionally occurs when lattice and magnetic degrees of…
Nonvolatile Nematic Order Manipulated by Strain and Magnetic Field in a Layered Antiferromagnet
Zili Feng, Weihang Lu, Tao Lu +6
The operation mechanism of nematic liquid crystals lies in the control of their optical properties by the orientation of underlying nematic directors. In analogy, electronic nemati…
Raman spectroscopic evidence for linearly dispersed nodes and magnetic ordering in the topological semimetal VNbS
Shreenanda Ghosh, Chris Lygouras, Zili Feng +3
Weyl semimetals are characterized by an electronic structure with linearly dispersed nodes and distinguished chirality, protected by broken inversion or time reversal symmetry. The…
TensorSymmetry: a package to get symmetry-adapted tensors disentangling spin-orbit coupling effect and establishing analytical relationship with magnetic order
Rui-Chun Xiao, Yuanjun Jin, Zhi-Fan Zhang +3
The symmetry-constrained response tensors on transport, optical, and electromagnetic effects are of central importance in condensed matter physics because they can guide experiment…
