Mott insulator and superfluid phases in bosonic superlattices

We study the ground-state phase diagram of boson chains on a 2-period superlattice using the density matrix renormalization group method. New insulators for commensurate densities were found, diferentiated by the arrangement of the particles in the unit cell, which was corroborated by analysis of...
