Our work on orientational melting of ion crystals is now published on Physical Review Letter! We studied the peculiar melting of our 2D crystals: the loss of crystallization along the angular direction and its dependence on particle number and impurities reveals the mesoscopic character of the observed transition. Our work paves the way to studies of thermodynamics of small systems and of quantum rotors. Read more on PRL! L. Duca, et al. |
