Abstract.

The equilibrium configurations of a macroscopic Wigner crystal (2D system of interacting charged balls, mechanically excited) and their evolution towards these equilibrium configurations are presented. In particular, the variations of the number of remaining dislocations at equilibrium according to the number of particles, confinement shape and temperature have been extensively explored. One important result is the exhibition of the rapid creation of an unique grain boundary and its shrinkage during the annealing.

  16. In previous studies we have shown that the equilibrium configurations of mesoscopic systems are in agreement with those calculated for Logarithmic interaction. Moreover we have been able to invalidate a published numerical ground configuration for N=17 particles, to show that this proposed configuration was in fact the first excited state and to suggest the actual ground state. Our experimental prediction was later confirmed numerically by the authors (the relative energy difference between the two configurations being 10−5). These indirect arguments (analytical direct derivation is a challenge) are very strong and have convinced us about the validity of the surprizing logarithmic interaction
