  Title Melting and evaporation in classical two-dimensional clusters confined by a Coulomb potential Type A1 Journal article
  Year (down) 2005 Publication Physical review : E : statistical, nonlinear, and soft matter physics Abbreviated Journal Phys Rev E

  Abstract The thermal properties of a two-dimensional classical cluster of negatively charged particles bound by a punctual positive charge are presented. The melting phenomenon is analyzed and the features which characterize such a solid-liquid transition are highlighted. We found that the presence of metastable states strongly modifies the melting scenario, and that the melting temperature of the system is determined by the height of the saddle point energy separating the ground state and the metastable state. Due to the particular type of confinement potential considered in this paper, we also found that, at sufficiently large temperature, the cluster can become thermally ionized.
