We theoretically investigate the process of splitting two-ion crystals insegmented Paul traps, i.e. the structural transition from two ions confined ina common well to ions confined in separate wells. The precise control of thisprocess by application of suitable voltage ramps to the trap segments isnon-trivial, as the harmonic confinement transiently vanishes during theprocess. This makes the ions strongly susceptible to background electric fieldnoise, and to static offset fields in the direction of the trap axis. Weanalyze the reasons why large energy transfers can occur, which are impulsiveacceleration, the presence of residual background fields and enhanced anomalousheating. For the impulsive acceleration, we identify the diabatic and adiabaticregimes, which are characterized by different scaling behavior of the energytransfer with respect to time. We propose a suitable control scheme based onexperimentally accessible parameters. Simulations are used to verify both thehigh sensitivity of the splitting result and the performance of our controlscheme. Finally, we analyze the impact of trap geometry parameters on thecrystal splitting process.
