dc.descriptionWe study the dynamics of persistent bosonic currents in closed-loop atom circuits in the form of ring lattices and under the action of time periodic driving. The closed-loop atom circuits are described by a Bose-Hubbard model in the presence of a Peierls phase and with periodic boundary conditions. We find that the motion of matter waves can be controlled with the help of an external driving only applied in one site of the ring lattice. For tuned values of the interaction strength between particles, we show that there exists a frequency range of the external driving where not only suppression but also reversion of the persistent bosonic currents is achieved. Applications of our results are discussed.
