Crystalline Phase

In 1938, Eugene Wignergif theorized that a collection of particles ionized with the same polarity would assume a crystalline configuration when its potential energy of repulsive Coulomb interactions was large relative to its kinetic energy.[4] Since Wuerker's 1959 observation of crystallization of charged aluminum particles, Wigner crystallization within a Paul trap has been demonstrated by laser-cooled Mg ions and Hg ions.[37]
