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…

Dissipative spin-boson model and Kondo effect in low dimensional quantum gases
A. Recati, P. O. Fedichev, W. Zwerger +2
We show that ultracold atoms confined in a quasi-1d trap can be used to study the dissipative spin-boson model with {\it tunable} tunneling splitting and strength of dissipation. I…
