Abstract: ZP1.00003 : Improved Shell models for screened Coulomb balls
(Inst. Theoretical Physics and Astrophysics, University Kiel, Germany)
Spherical Coulomb crystals in dusty plasmas  are well described by an isotropic Yukawa-type pair interaction and an external parabolic confinement as was shown by extensive molecular dynamics simulations . A much simpler description is possible with analytical shell models which have been derived for Yukawas plasmas in [3,4]. Here we analyze improved Yukawa shell models which include correlations along the lines proposed for Coulomb crystals in . The shell configurations are efficiently evaluated using a Monte Carlo procedure.  O. Arp, A. Piel and A. Melzer, Phys. Rev. Lett. 93, 165004 (2004).  M. Bonitz, D. Block, O. Arp, V. Golunychiy, H.
