Phys. Rev. Lett. 100, 113401 (2008) [4 pages]Melting of Trapped Few-Particle SystemsReceived 8 November 2007; published 20 March 2008 In small confined systems predictions for the melting point strongly depend on the choice of quantity and on the way it is computed, even yielding divergent and ambiguous results. We present a very simple quantity that allows us to control these problems—the variance of the block averaged interparticle distance fluctuations. © 2008 The American Physical Society URL:
