Observing the emergence of chaos in a many-particle quantum system
J. Tomkovič, W. Muessel, H. Strobel +4
Accessing the connection between classical chaos and quantum many-body systems has been a long-standing experimental challenge. Here, we investigate the onset of chaos in periodica…
Observation of scaling in the dynamics of a strongly quenched quantum gas
Eike Nicklas, Markus Karl, Moritz Höfer +6
We report on the experimental observation of scaling in the time evolution following a sudden quench into the vicinity of a quantum critical point. The experimental system, a two-c…
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…
