Abstract
The Nonequilibrium Dynamics Of Small Boson Ensembles In A One-Dimensional Optical Lattice Is Explored Upon A Sudden Quench Of An Additional Harmonic Trap From Strong To Weak Confinement. We Find That The Competition Between The Initial Localization And The Repulsive Interaction Leads To A Resonant Response Of The System For Intermediate Quench Amplitudes, Corresponding To Avoided Crossings In The Many-Body Eigenspectrum With Varying Final Trap Frequency. In Particular, We Show That These Avoided Crossings Can Be Utilized To Prepare The System In A Desired State. The Dynamical Response Is Shown To Depend On Both The Interaction Strength As Well As The Number Of Atoms Manifesting The Many-Body Nature Of The Tunneling Dynamics.
