Fisher Information and entanglement of non-Gaussian spin states
Helmut Strobel, Wolfgang Muessel, Daniel Linnemann +5
Entanglement is the key quantum resource for improving measurement sensitivity beyond classical limits. However, the production of entanglement in mesoscopic atomic systems has bee…
Twist-and-Turn Spin Squeezing in Bose-Einstein Condensates
W. Muessel, H. Strobel, D. Linnemann +3
We experimentally demonstrate an alternative method for the dynamic generation of atomic spin squeezing, building on the interplay between linear coupling and nonlinear phase evolu…
Observation of the Berezinskii-Kosterlitz-Thouless Phase Transition in an Ultracold Fermi Gas
P. A. Murthy, I. Boettcher, L. Bayha +7
We experimentally investigate the first-order correlation function of a trapped Fermi gas in the two-dimensional BEC-BCS crossover. We observe a transition to a low-temperature sup…
Charm, Beauty and Top at HERA
O. Behnke, A. Geiser, M. Lisovyi
Results on open charm and beauty production and on the search for top production in high-energy electron-proton collisions at HERA are reviewed. This includes a discussion of relev…
Euro-VO - Coordination of Virtual Observatory activities in Europe
Francoise Genova, Mark G. Allen, Christophe Arviset +4
The European Virtual Observatory Euro-VO has been coordinating European VO activities through a series of projects co-funded by the European Commission over the last 15 years. The…
Nearby Clumpy, Gas Rich, Star Forming Galaxies: Local Analogs of High Redshift Clumpy Galaxies
C. A. Garland, D. J. Pisano, M. -M. Mac Low +3
Luminous compact blue galaxies (LCBGs) have enhanced star formation rates and compact morphologies. We combine Sloan Digital Sky Survey data with HI data of 29 LCBGs at redshift z~…
