Controllability of ultracold atomic gases has reached an unprecedented level,allowing for experimental realization of the long-sought-after Thouless pump,which can be interpreted as a dynamical quantum Hall effect. On the other hand,Weyl semimetals and Weyl nodal line semimetals with touching points and ringsin band structures have sparked tremendous interest in various fields in thepast few years. Here, we show that dynamical Weyl points and dynamical 4D Weylnodal rings, which are protected by the first Chern number on a parametersurface formed by quasi-momentum and time, emerge in a two-dimensional andthree-dimensional system, respectively. We find that the topological pumpoccurs in these systems but the amount of pumped particles is not quantized andcan be continuously tuned by controlling experimental parameters over a widerange. We also propose an experimental scheme to realize the dynamical Weylpoints and 4D Weyl nodal rings and to observe their corresponding topologicalpump in cold atomic gases.
