WebJul 27, 2024 · For an adiabatic Thouless pump the number of particles transported by one lattice constant per cycle is given by the Berry phase, i.e., the Berry flux penetrating a … Webt. e. Pumping and stirring effects in quantum physics have counterparts in purely classical stochastic and dissipative processes. [1] The studies of quantum pumping [2] [3] and of quantum stirring [4] emphasize the role of quantum interference in the analysis of the induced current. A major objective is to calculate the amount of transported ...
