A general-purpose cooling technique that achieves mK-temperatures for species without suitable laser transitions is of interest for a wide range of AMO experiments with trapped charged particles. We present recently published results on sympathetically cooling a single proton in a Penning trap with laser-cooled beryllium ions located in a different trap (Bohman et al., Nature, 2021). Coupling is achieved via image currents induced in adjacent trap electrodes, allowing a macroscopic separation between the two species. This techniques allows cooling of any trapped charged particle, with a particular focus on exotic species such as antimatter or highly-charged ions.
This talk will cover the most recent experimental results as well as future prospects based on simulation work.
