A SIMPLE MODEL FOR AN ULTRACOLD PLASMA

Abstract

We consider an ultracold plasma composed of the same number of electrons and bosonic ions, at zero temperature. We calculate the ion and electron densities taking the long range interactions into account using a modied Thomas-Fermi ap- proximation. We assume that ions are trapped by harmonic trap while electrons are only trapped by the ion cloud. For a cloud that contains 10 4 electrons and 10 4 ions conned
