Ion traps are versatile tools for experiments in various fields, such as spectroscopy, quantum computing, molecular physics and biophysics [1]. Even though there is a large interest in the formation of various structures like ion crystals [2] or zig-zag configurations [3,4] the underlying dynamics are often not well understood. Here we investigate the dynamics of trapped ions in a two dimensional double well potential. The initial state of the ions in our setup is given by well separeted zig-zag configurations in both wells. After quenching the barrier between the wells various structures including the formation of lines and partial revivals to the initial zig-zag configuration can be observed to alternate with phases of irregular motion in the course of the time evolution.
