Journal ArticleDOI
Nonlinear atom interferometer surpasses classical precision limit
TL;DR: It is shown experimentally that the classical precision limit can be surpassed using nonlinear atom interferometry with a Bose–Einstein condensate and the results provide information on the many-particle quantum state, and imply the entanglement of 170 atoms.
Journal ArticleDOI
Classical Bifurcation at the Transition from Rabi to Josephson Dynamics
TL;DR: The results suggest that the internal bosonic Josephson effect in a rubidium spinor Bose-Einstein condensate is a model system which can be tuned from classical to the quantum regime and thus is an important step towards the experimental investigation of entanglement generation close to critical points.
Journal ArticleDOI
Atomic homodyne detection of continuous-variable entangled twin-atom states
Christian Gross,Helmut Strobel,Eike Nicklas,Tilman Zibold,Nir Bar-Gill,Nir Bar-Gill,Gershon Kurizki,Markus K. Oberthaler +7 more
TL;DR: The realization of an atomic analogue to homodyne detection for the measurement of matter-wave quadratures and the application of this technique to a quantum state produced by spin-changing collisions in a Bose–Einstein condensate reveals continuous-variable entanglement, as well as the twin-atom character of the state.
Journal ArticleDOI
Observation of scaling in the dynamics of a strongly quenched quantum gas
Eike Nicklas,Markus Karl,Moritz Höfer,Aisling Johnson,W. Muessel,Helmut Strobel,Jiří Tomkovič,Thomas Gasenzer,Markus K. Oberthaler +8 more
TL;DR: In this article, the experimental observation of scaling in the time evolution following a sudden quench into the vicinity of a quantum critical point is reported. But the experimental system, a two-component Bose gas with coherent exchange between the constituents, allows for the necessary high level of control of parameters as well as the access to time-resolved spatial correlation functions.
Journal ArticleDOI
Rabi flopping induces spatial demixing dynamics.
Eike Nicklas,Helmut Strobel,Tilman Zibold,Christian Gross,B. A. Malomed,Panos Kevrekidis,Markus K. Oberthaler +6 more
TL;DR: The observed amplitude reduction of the Rabi oscillations can be understood as a result of demixing dynamics of dressed states as experimentally confirmed by reconstructing the spatial profile of dressed state amplitudes.
