Topological pumps enable robust transports of topological states when the system
parameters are varied in a cyclic process. The reported topological pumps are protected by …

Unconventional Dirac-Weyl semimetal with ultralong surface arc in phononic crystals

P Wu, F Gao, X **ang, C Zheng, YG Peng, XF Zhu - Physical Review B, 2024 - APS
The fascinating properties of unconventional Dirac and Weyl nodes in crystalline systems,
carrying a topological charge of±2, have captured the attention of researchers. Here …

Floquet-Anderson localization in the Thouless pump and how to avoid it

A Grabarits, A Takács, IC Fulga, JK Asbóth - Physical Review B, 2024 - APS
We investigate numerically how on-site disorder affects conduction in the periodically driven
Rice-Mele model, a prototypical realization of the Thouless pump. Although the pump is …
