Journal ArticleDOI
In situ observation of incompressible Mott-insulating domains in ultracold atomic gases
TL;DR: In this paper, a two-dimensional ultracold Bose gas as it crosses the superfluid to Mott insulator transition is shown to exhibit a strong suppression in the insulator domain and suppressed density fluctuations in the Mott domain.
Journal ArticleDOI
Precise determination of 6Li cold collision parameters by radio-frequency spectroscopy on weakly bound molecules.

TL;DR: Radio-frequency spectroscopy is employed on weakly bound (6)Li(2) molecules to precisely determine the molecular binding energies and the energy splittings between molecular states for different magnetic fields.
Journal ArticleDOI
Observation of scale invariance and universality in two-dimensional Bose gases.
TL;DR: In situ density and density-fluctuation measurements of two-dimensional Bose gases of caesium at different temperatures and interaction strengths are reported, observing scale-invariant, universal behaviours, and provide evidence for growing density–density correlations in the fluctuation region.
Journal ArticleDOI
Beyond optical molasses: 3D raman sideband cooling of atomic cesium to high phase-space density
TL;DR: A simple, general purpose method to cool neutral atoms based on 3D degenerate Raman sideband cooling in optical lattices and remains efficient even at densities where the mean lattice site occupation is close to unity.

In-situ Observation of Incompressible Mott-Insulating Domains of Ultracold Atomic Gases
TL;DR: In this article, the density profile of a two-dimensional Mott insulator formed by ultracold atoms in an optical lattice was measured using high-resolution absorption imaging.
