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…
Quasihole dynamics as a detection tool for quantum Hall phases
Tobias Graß, Bruno Juliá-Díaz, Maciej Lewenstein
Existing techniques for synthesizing gauge fields are able to bring a two-dimensional cloud of harmonically trapped bosonic atoms into a regime where the occupied single-particle s…
Quantum control of spin-correlations in ultracold lattice gases
P. Hauke, R. J. Sewell, M. W. Mitchell +1
We demonstrate that it is possible to prepare a lattice gas of ultracold atoms with a desired non-classical spin-correlation function using atom-light interaction of the kind routi…
Entanglement entropy for the long range Ising chain
Thomas Koffel, M. Lewenstein, Luca Tagliacozzo
We consider the Ising model in a transverse field with long-range antiferromagnetic interactions that decay as a power law with their distance. We study both the phase diagram and…
