Variational ansatz for the superfluid Mott-insulator transition in optical lattices

J. J. Garcia-Ripoll, J. I. Cirac, P. Zoller +3

We develop a variational wave function for the ground state of a one-dimensional bosonic lattice gas. The variational theory is initally developed for the quantum rotor model and l…
