Abstract
The Out-Of-Equilibrium Dynamics Of Interaction Quenched Finite Ultracold Bosonic Ensembles In Periodically Driven One-Dimensional Optical Lattices Is Investigated. It Is Shown That Periodic Driving Enforces The Bosons In The Outer Wells Of The Finite Lattice To Exhibit Out-Of-Phase Dipolelike Modes, While In The Central Well The Atomic Cloud Experiences A Local Breathing Mode. The Dynamical Behavior Is Investigated With Varying Driving Frequencies, Revealing Resonantlike Behavior Of The Intrawell Dynamics. An Interaction Quench In The Periodically Driven Lattice Gives Rise To Admixtures Of Different Excitations In The Outer Wells, Enhanced Breathing In The Center, And Amplification Of The Tunneling Dynamics. We Then Observe Multiple Resonances Between The Inter- And The Intrawell Dynamics At Different Quench Amplitudes, With The Position Of The Resonances Being Tunable Via The Driving Frequency. Our Results Pave The Way For Future Investigations Of The Use Of Combined Driving Protocols In Order To Excite Different Inter- And Intrawell Modes And To Subsequently Control Them.
