Rotation of the Orientation of the Wave Function Distribution of a Charged Particle and its Utilization

We describe a method for selecting and sorting particles in an ion trap with respect to charge and mass. The method exploits a so-called shortcut to adiabatic passage, specifically the fast-forward field protocol, to design an electromagnetic field that rotates the spatial orientation of the wave function of the desired ion. The electromagnetic field forces ions that have different mass and electrical charge from the desired ionic species out of the trapping potential without exciting the desired ionic species, leaving the latter undisturbed in the trap.
