Evidence for Universal Four-Body States Tied to an Efimov Trimer

F. Ferlaino, S. Knoop, M. Berninger +4

We report on the measurement of four-body recombination rate coefficients in an atomic gas. Our results obtained with an ultracold sample of cesium atoms at negative scattering len…

Lifetime of angular momentum in a rotating strongly interacting Fermi gas

S. Riedl, E. R. Sanchez Guajardo, C. Kohstall +2

We investigate the lifetime of angular momentum in an ultracold strongly interacting Fermi gas, confined in a trap with controllable ellipticity. To determine the angular momentum…

Trap modulation spectroscopy of the Mott-insulator transition in optical lattices

H. Lignier, A. Zenesini, D. Ciampini +5

We introduce a new technique to probe the properties of an interacting cold atomic gas that can be viewed as a dynamical compressibility measurement. We apply this technique to the…

Atomic three-body loss as a dynamical three-body interaction

A. J. Daley, J. M. Taylor, S. Diehl +2

We discuss how large three-body loss of atoms in an optical lattice can give rise to effective hard-core three-body interactions. For bosons, in addition to the usual atomic superf…

Dipole oscillations of confined lattice bosons in one dimension

Simone Montangero, Rosario Fazio, Peter Zoller +1

We study the dynamics of a non-integrable system comprising interacting cold bosons trapped in an optical lattice in one-dimension by means of exact time-dependent numerical DMRG t…

Determination of atomic scattering lengths from measurements of molecular binding energies near Feshbach resonances

A. D. Lange, K. Pilch, A. Prantner +5

We present an analytic model to calculate the atomic scattering length near a Feshbach resonance from data on the molecular binding energy. Our approach considers finite-range squa…
