Universal Quantized Berry-Dipole Flat Bands
Qingyang Mo, Shuang Zhang
Perfectly flat bands with nontrivial quantum geometry have emerged as a frontier for exotic topological phenomena and superconductors. Here, we unveil a universal family of quantiz…

Demonstration of returning Thouless pump in a Berry dipole system
Qingyang Mo, Shanjun Liang, Xiangke Lan +2
The Thouless pump, a cornerstone of topological physics, enables unidirectional quantized wave/particle transport via geometric Berry phase engineering in periodically driven syste…

Tensor-monopole-induced topological boundary effects in four-dimensional acoustic metamaterials
Qingyang Mo, Shanjun Liang, Cuicui Lu +2
Gauge field theory provides the mathematical and conceptual framework to describe and understand topological singularities such as Weyl points and magnetic monopoles. While singula…
