Quantized topological Anderson-Thouless pump
Yi-Piao Wu, Ling-Zhi Tang, Guo-Qing Zhang, Dan-Wei Zhang
Abstract
The authors propose a counterintuitive topological pump induced by disorder from a trivial pump in the clean limit. They show that such a topological pump is generic from static to dynamical disorder cases, from noninteracting to interacting regimes, and even exhibits in higher-order topological systems.
