(color online) (a) Quasi-energy spectrum for triple quantum dots with and W = 0.1. Symbols indicate the sorting of the corresponding Floquet state: red circles, green squares, and black triangles represent inner-dot states, inter-dot states, and wide separated states, respectively. (b) The long-time averaged occupation probability for the triple quantum dots with electrons, initialized in state . The dash line indicates the values of the peak corresponding to the zero point of the Bessel function J₀.
