Melting of crystals in two dimensions

U Gasser, C Eisenmann, G Maret, P Keim - ChemPhysChem, 2010 - Wiley Online Library
While the melting of crystals is in general not understood in detail on a microscopic scale,
there is a microscopic theory for a class of two‐dimensional crystals, which is based on the …

Observation of condensed phases of quasiplanar core-softened colloids

N Osterman, D Babič, I Poberaj, J Dobnikar, P Ziherl - Physical review letters, 2007 - APS
