Topological charge pumping in a one-dimensional optical lattice
WebJan 18, 2016 · In the quantum pump, the pumped charge is connected to the two-dimensional topological invariant, the Chern number ν, which was first introduced in the context of the integer quantum Hall effect ... Webtopological charge pumping by calculating its Chern number and ab initio simulation of the pumping process. Compared with the corresponding classical dynamics, we show that quantum effects are crucial for the topological protection of the quantized charge pumping. We then con-sider the effect of a harmonic trap and predict the topo- c.f. stands for
