Anomalous‐Chern Steering of Topological Nonreciprocal Guided Waves
Romain Christophe Rémy Fleury, Haoye Qin, Zhechen Zhang, Qiaolu Chen
Nonreciprocal topological edge states based on external magnetic bias have been regarded as the last resort for genuine unidirectional wave transport, showing superior robustness over topological states with preserved time-reversal symmetry. However, fast ...
2024Learning Dynamics of Spring-Mass Models with Physics-Informed Graph Neural Networks
Olga Fink, Vinay Sharma, Manav Manav
We propose a physics-informed message-passing graph neural network (GNN) for learning the dynamics of springmass systems. The proposed method embeds the underlying physics directly into the message-passing scheme of the GNN. We compare the new scheme with ...
Research Publishing2023Quasi-symmetry-protected topology in a semi-metal
Philip Johannes Walter Moll, Matthias Carsten Putzke, Yi-Chiang Sun, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez
The concept of quasi-symmetry-a perturbatively small deviation from exact symmetry-is introduced and leads to topological materials with strong resilience to perturbations. The crystal symmetry of a material dictates the type of topological band structure ...
NATURE PORTFOLIO2022Supersymmetries in nonequilibrium Langevin dynamics
Stochastic phenomena are often described by Langevin equations, which serve as a mesoscopic model for microscopic dynamics. It has been known since the work of Parisi and Sourlas that reversible (or equilibrium) dynamics present supersymmetries (SUSYs). Th ...
