Abstract

We study a variant of the generalized Thomson problem in which n particles are confined to a neutral sphere and interacting by a 1/ r γ potential. It is found that for γ ⩽ 1 the electrostatic repulsion expels all the charges to the surface of the sphere. However, for γ > 1 and n > n c (γ) occupation of the bulk becomes energetically favorable. It is curious to note that the Coulomb law lies exactly on the interface between these two regimes.
