DESCRIPTION:We show that a two-dimensional (2D) array of 1D interacting bo
 son tubes has a deconfinement transition between a 1D Mott insulator and a
  3D superfluid for commensurate fillings and a dimensional crossover for t
 he incommensurate case. We determine the phase diagram and excitations of 
 this system and discuss the consequences for Bose condensates loaded in 2D
  optical lattices.\n\nReferences:\n\nHo et al\, PRL 92\,130405 (2004)\n\nC
