Rubidium 1 is our first rubidium experiment and has been used for a range of lattice experiments.  These experiments include “single-quanta” or “mean-field” experiments such as: the pattered loading of atoms into every-third lattice site in an optical lattice; the decay of vibrational motion in a 1D optical lattice; and the long-time evolution of atoms in an optical lattice.  Other experiments have involved properties of the many-body system such as: correlations in a 1D Bose gas; damping in 1D lattice systems; and the Mott-Insulator to Superfluid transition in 2D.  More recently we developed a new lattice called the “double well lattice” in which we have: studied the coherent dynamics of few-atom systems; addressed atoms in “every left” or “every right” lattice; and even implemented a 2-qubit gate.
