  • The formation of defects in numerous systems is believed to follow universal scaling laws arising from the Kibble–Zurek mechanism. Ulm et al.measure this scaling law for defects created in ion Coulomb crystals, confirming the predicted behaviour for a system of 16 ions.

  • Superlubricity has been predicted and observed at an atomistic level, yet its dynamics is not well understood due to the lack ofin situ characterization of contact surfaces. Kiethe et al. use a trapped two-dimensional ion crystal as a model for the study of nanofriction in self-organized structures.

  • The Kibble–Zurek mechanism describes the formation of topological defects in systems undergoing continuous phase transitions, and predicts a power law for their density. Pyka et al. create defects in ion coulomb crystals and observe their scaling behaviour in the context of the Kibble–Zurek theory.
