One can gain deeper insight into complex quantum dynamics via experimentally simulating the quantum behaviour of interest in another quantum system, where not all but the relevant parameters and interactions can be controlled and robust effects detected sufficiently well.
We report the trapping of a single ion in an optical dipole trap for a duration on the order of milliseconds. After the dipole trap is loaded by a regular Paul trap, the latter is turned off. Due to the sensitivity of the charged particle to voltages, the dipole forces required are orders of magnitudes above the ones required for atomic dipole traps. We found that we can achieve this by decreasing the detuning from resonance. However, this causes the increase of various heating effects like dipole heating and recoil heating, limiting the trapping duration. Therefore one has to find a trade-off between strong dipole forces and long trapping durations.
We aim to merge the advantages of quantum simulations with atoms and ions by confining them in the identical dipole trap/optical lattice. This renders it possible to investigate for instance atom-ion interactions or to form anharmonic potentials, a tool for scalable quantum simulations.
