Mott-Superfluid transition in bosonic ladders
arXiv:cond-mat/0101214 · doi:10.1103/PhysRevB.63.180508
Abstract
We show that in a commensurate bosonic ladder, a quantum phase transition occurs between a Mott insulator and a superfluid when interchain hopping increases. We analyse the properties of such a transition as well as the physical properties of the two phases. We discuss the physical consequences for experimental systems such as Josephson Junction arrays.
