title: Two-dimensional condensed phases from particles with tunable interactions.
abstract: We present a conceptually simple experimental model for condensed phases, consisting of an ensemble of identical magnetic dipoles on a vibrating bed. The model combines tunable and accurately known pair potentials, equilibration times of seconds, and lattice structure and dynamics visible to the naked eye. Fundamental ensemble properties--specifically phonon propagation, edge relaxation, and binary condensation--are directly observed and quantitatively linked to the underlying pair potential.
