Production of quantum degenerate strontium gases: Larger, better, faster, colder
Simon Stellmer, Rudolf Grimm, Florian Schreck
We report on an improved scheme to generate Bose-Einstein condensates (BECs) and degenerate Fermi gases of strontium. This scheme allows us to create quantum gases with higher atom…
Feshbach resonances, weakly bound molecular states and coupled-channel potentials for cesium at high magnetic fields
Martin Berninger, Alessandro Zenesini, Bo Huang +6
We explore the scattering properties of ultracold ground-state Cs atoms at magnetic fields between 450 G (45 mT) and 1000 G. We identify 17 new Feshbach resonances, including two v…
Direct imaging of topological edge states in cold-atom systems
N. Goldman, J. Dalibard, A. Dauphin +4
Detecting topological order in cold-atom experiments is an ongoing challenge, the resolution of which offers novel perspectives on topological matter. In material systems, unambigu…
Magnetic properties of commensurate Bose-Bose mixtures in one-dimensional optical lattices

Keldysh approach for non-equilibrium phase transitions in quantum optics: beyond the Dicke model in optical cavities
Emanuele G. Dalla Torre, Sebastian Diehl, Mikhail D. Lukin +2
We investigate non-equilibrium phase transitions for driven atomic ensembles, interacting with a cavity mode, coupled to a Markovian dissipative bath. In the thermodynamic limit an…
Two-dimensional Bose gases near resonance: universal three-body effects

We report in this Letter the results of our investigation of 2D Bose gases beyond the dilute limit emphasizing the role played by three-body scattering events. We demonstrate that…

We derive the universal high momentum factorization of the fermion self-energy in the BCS-BEC crossover of ultracold atoms using nonperturbative quantum field theoretical methods.…

Recent experimental breakthroughs in trapping, cooling and controlling ultracold gases of polar molecules, magnetic and Rydberg atoms have paved the way toward the investigation of…
Dressed, noise- or disorder- resilient optical lattices
Hannes Pichler, Johannes Schachenmayer, Jonathan Simon +2
External noise is inherent in any quantum system, and can have especially strong effects for systems exhibiting sensitive many-body phenomena. We show how a dressed lattice scheme…
