| contents | Molecular dynamics simulations of two-dimensional clusters of charges Simara S. de Moraes J. Ricardo de Sousa Hidemberg Ordozgoith da Frota Débora Coimbra Física, Astronomía y Matemáticas We study structural and spectral properties of finite classical systems of N two-dimensional charged particles,confined by a parabolic potential ∝ rn, and interacting via inverse power-law potentials ∝ 1/rn . Moleculardynamics simulations are performed for different cluster sizes (N = 30 to 230) and n, n values 1, 2, 3 and 10.We also analyze the phase transition from a ring-like configuration to aWigner structure as a function of parametern and anisotropy. We compare our results with Monte Carlo simulations of Bedanov and Peeters, obtaininggood agreement. In addition, we determine the Voronoi structure of the cluster. Our work complements that ofCandido, Rino and Studart, who analyzed confinement in a screened parabolic potential. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434214 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.34 |
