Many-Body Physics with Ultracold Gases
This paper reviews recent experimental and theoretical progress concerning many-body phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling descriptions, such asExpand
Nuclear Induction
electric accelerating fields are to be obtained. by replacing the usual "dee" assembly and acceleration chamber by a cavity resonator, similar to types now commonly employed in radar. The use of suchExpand
Quantum phase transition from a superfluid to a Mott insulator in a gas of ultracold atoms
This work observes a quantum phase transition in a Bose–Einstein condensate with repulsive interactions, held in a three-dimensional optical lattice potential, and can induce reversible changes between the two ground states of the system. Expand
Single-atom-resolved fluorescence imaging of an atomic Mott insulator
Fluorescence imaging of strongly interacting bosonic Mott insulators in an optical lattice with single-atom and single-site resolution is reported, which fully reconstructs the atom distribution on the lattice and identifies individual excitations with high fidelity. Expand
Realization of the Hofstadter Hamiltonian with ultracold atoms in optical lattices.
It is shown that for two atomic spin states with opposite magnetic moments, the experimental implementation of an optical lattice that allows for the generation of large homogeneous and tunable artificial magnetic fields with ultracold atoms naturally realizes the time-reversal-symmetric Hamiltonian underlying the quantum spin Hall effect.

Ultracold quantum gases in optical lattices
Artificial crystals of light, consisting of hundreds of thousands of optical microtraps, are routinely created by interfering optical laser beams. These so-called optical lattices act as versatileExpand
Collapse and revival of the matter wave field of a Bose–Einstein condensate
It is observed that the matter wave field of the Bose–Einstein condensate undergoes a periodic series of collapses and revivals; this behaviour is directly demonstrated in the dynamical evolution of the multiple matter wave interference pattern. Expand
Observation of many-body localization of interacting fermions in a quasirandom optical lattice
This experiment experimentally observed this nonergodic evolution for interacting fermions in a one-dimensional quasirandom optical lattice and identified the MBL transition through the relaxation dynamics of an initially prepared charge density wave. Expand
Single-spin addressing in an atomic Mott insulator
This work was able to flip the spin of individual atoms in a Mott insulator with sub-diffraction-limited resolution, well below the lattice spacing, and created arbitrary spin patterns by sequentially addressing selected lattice sites after freezing out the atom distribution. Expand
