Shear-Mode Raman Imaging of Ferroelectric Switching in Multilayer 3-MoS
Yulu Liu, Kenji Watanabe, Takashi Taniguchi +1
We use shear-mode Raman imaging to track ferroelectric switching in multilayer 3-MoS. Within a single flake, mechanically segmented regions respond independently and follow…
Symmetry Analysis of Magnetoelectric Coupling Effect in All Point Groups
Xinhai Tu, Di Wang, Hanjing Zhou +4
Symmetry analysis provides crucial insights into the magnetoelectric coupling effect in type-II multiferroics. In this Letter, we comprehensively investigate couplings between elec…
Ab Initio Theory of Phonon Magnetic Moment Induced by Electron-Phonon Coupling in Magnetic Materials
Fuyi Wang, Xinqi Liu, Hong Sun +5
Circularly polarized phonons, characterized by nonzero angular momenta and magnetic moments, have attracted extensive attention. However, a long-standing critical issue in this fie…
Interlayer Hopping between Surface Mott Insulator and Bulk Band Insulator in layered 1T-TaS_{2}
Zijian Lin, Jie Li, Xiaodong Cao +7
In condensed matter physics, various mechanisms give rise to distinct insulating phases. The competition and interplay between these phases remain elusive, even for the seemingly m…
Realization of Hopf-link structure in phonon spectra: Symmetry guidance and High-throughput investigation
Houhao Wang, Licheng Zhang, Ruixi Pu +2
The realization of Hopf-link structure in the Brillouin zone is rather rare hindering the comprehensive exploration and understanding of such exotic nodal loop geometry. Here we fi…
Absence of altermagnetic spin splitting character in rutile oxide RuO
Jiayu Liu, Jie Zhan, Tongrui Li +19
Rutile RuO has been posited as a potential -wave altermagnetism candidate, with a predicted significant spin splitting up to 1.4 eV. Despite accumulating theoretical predict…
