Density profile of confined charged particles — Jeffry Wrighton1, James Dufty1, Christian Henning2, •Michael Bonitz2, and Hanno Kählert2 — 1Department of Physics, University of Florida, Gainesville, FL 32611 — 2Institut für Theoretische Physik und Astrophysik, Christian-Albrechts Universiät zu Kiel, 24098 Kiel
The density profile of a finite number of identical classical charged particles confined in a trapping potential is computed analytically and numerically. The results bridge the gap between the temperature limit given by the Boltzmann factor and the ground state result [1,2] given by a step profile. Preliminary results in mean-field approximation [3] are discussed further, and then extended to include strong correlations in the framework of the hypernetted chain approximation.
