HIGHLIGHTS
- who: Yongguan Ke from the School Sen University (Zhuhai Campus), Zhuhai, China have published the paper: Topological pumping assisted by Bloch oscillations, in the Journal: (JOURNAL) of 27/07/2020
- what: Of particular relevance to this work, the nonquantized geometric pumping in a lattice can be determined by the Berry curvature at a certain momentum value , whereas the quantized Thouless pumping yields a topological invariant, namely, the Chern_number of a band on a two-dimensional torus formed by the quasimomentum and the time variable as a second synthetic dimension. The authors propose an experimentally friendly . . .
