Unconventional relativistic spin polarization of electronic bands in an altermagnet
A. Dal Din, D. A. Usanov, L. Šmejkal +22
Altermagnetism is a recently identified phase with a d, g or i-wave spin symmetry of magnetic ordering. Its discovery opens new research fronts at intersections of magnetism and sp…
CryoDyna: Multiscale end-to-end modeling of cryo-EM macromolecule dynamics with physics-aware neural network
Chengwei Zhang, Shimian Li, Yihao Niu +4
Single-particle cryo-EM has transformed structural biology but still faces challenges in resolving conformational heterogeneity at atomic resolution. Existing cryo-EM heterogeneity…
Parametric resonance and nonlinear dynamics in a coupled double-pendulum system
Yusheng Niu, Yixian Liu, Hongyan Fan +2
Nonlinear dynamics plays a significant role in interdisciplinary fields spanning biology, engineering, mathematics, and physics. Under small-amplitude approximations, certain nonli…
Time delay of mean field interaction in thermal Rydberg atomic gas
Yuzhuo Wang, Tianxiong Gao, Yufan Niu +5
Mean field theory is commonly employed to study nonequilibrium dynamics in hot Rydberg atomic ensembles, but the fundamental mechanism behind the generation of the mean-field inter…
Altermagnetism imaged and controlled down to the nanoscale
O. J. Amin, A. Dal Din, E. Golias +17
Nanoscale detection and control of the magnetic order underpins a broad spectrum of fundamental research and practical device applications. The key principle involved is the breaki…
