Phys. Rev. Lett. 93, 263602 (2004) [4 pages]Bose-Einstein Condensation and Strong-Correlation Behavior of Phonons in Ion TrapsReceived 2 September 2004; published 20 December 2004 We show that the dynamics of phonons in a set of trapped ions interacting with lasers is described by a Bose-Hubbard model whose parameters can be externally adjusted. We investigate the possibility of observing several quantum many-body phenomena, including Bose-Einstein condensation as well as a superfluid-Mott insulator quantum phase transition. © 2004 The American Physical Society URL:
