Dynamics and thermodynamics of ultracold ion chains in harmonic traps at low temperatures are discussed. The spectrum of the linear excitations and the thermodynamic properties are considered in view of a properly defined thermodynamic limit, at which they reproduce the ones of a homogeneous Coulomb chain. The basic assumptions of this theory are discussed under the conditions of experimental realizations. © 2006 IOP Publishing Ltd.
