Abstract
The Correlated Nonequilibrium Quantum Dynamics Following A Multiple Interaction Quench Protocol For Few-Bosonic Ensembles Confined In Finite Optical Lattices Is Investigated. The Quenches Give Rise To An Interwell Tunneling And Excite The Cradle And A Breathing Mode. Several Tunneling Pathways Open During The Time Interval Of Increased Interactions, While Only A Few Occur When The System Is Quenched Back To Its Original Interaction Strength. The Cradle Mode, However, Persists During And In Between The Quenches, While The Breathing Mode Possesses Distinct Frequencies. The Occupation Of Excited Bands Is Explored In Detail Revealing A Monotonic Behavior With Increasing Quench Amplitude And A Nonlinear Dependence On The Duration Of The Application Of The Quenched Interaction Strength. Finally, A Periodic Population Transfer Between Momenta For Quenches Of Increasing Interaction Is Observed, With A Power-Law Frequency Dependence On The Quench Amplitude. Our Results Open The Possibility To Dynamically Manipulate Various Excited Modes Of The Bosonic System.
