A Route to Nonrelativistic Altermagnetic Spin Splitting via Ultrafast Light
Huang-Zhao-Xiang Chen, Lin-Ding Yuan, Wen-Hao Liu +3
We identify a nonequilibrium route for generating altermagnetic spin splitting in antiferromagnet by ultrafast light. Unlike existing strategies, this route does not require relati…

Origin of Suppressed Ferroelectricity in k-GaO: Interplay Between Polarization and Lattice Domain Walls
Yonghao Zhu, Zhi Wang, Junwei Luo +1
The large discrepancy between experimental and theoretical remanent polarization and coercive field limits the applications of wide-band-gap ferroelectric materials. Here, using a…

Ultrafast dynamics of atomic correlated disordering in photoinduced VO
Wen-Hao Liu, Feng-Wu Guo, Lin-Wang Wang +1
Recent experiments suggest that atomic disordering dynamics are more universal than conventional coherent processes in photoinduced phase transitions (PIPTs), yet its mechanism rem…
