Einstein-Podolsky-Rosen experiment with two Bose-Einstein condensates
Paolo Colciaghi, Yifan Li, Philipp Treutlein +1
In 1935, Einstein, Podolsky and Rosen (EPR) conceived a Gedankenexperiment which became a cornerstone of quantum technology and still challenges our understanding of reality and lo…
Fundamental limit of phase coherence in two-component Bose-Einstein condensates
Yifan Li, Krzysztof Pawłowski, Boris Décamps +4
We experimentally and theoretically study phase coherence in two-component Bose-Einstein condensates of atoms on an atom chip. Using Ramsey interferometry we measur…
Entanglement between identical particles is a useful and consistent resource
Benjamin Morris, Benjamin Yadin, Matteo Fadel +3
The existence of fundamentally identical particles represents a foundational distinction between classical and quantum mechanics. Due to their exchange symmetry, identical particle…
Spatial entanglement patterns and Einstein-Podolsky-Rosen steering in a Bose-Einstein condensate
Matteo Fadel, Tilman Zibold, Boris Décamps +1
Many-particle entanglement is a fundamental concept of quantum physics that still presents conceptual challenges. While spin-squeezed and other nonclassical states of atomic ensemb…
Stepwise Bose-Einstein condensation in a spinor gas
C. Frapolli, T. Zibold, A. Invernizzi +3
We observe multi-step condensation of sodium atoms with spin , where the different Zeeman components condense sequentially as the temperature decreases. The prec…
Shortcut to adiabaticity in spinor condensates
Arnau Sala, David López Núñez, Joan Martorell +5
We devise a method to shortcut the adiabatic evolution of a spin-1 Bose gas with an external magnetic field as the control parameter. An initial many-body state with almost all bos…
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…
Spin nematic order in antiferromagnetic spinor condensates
Tilman Zibold, Vincent Corre, Camille Frapolli +3
Large spin systems can exhibit unconventional types of magnetic ordering different from the ferromagnetic or Néel-like antiferromagnetic order commonly found in spin 1/2 systems. S…
Spin fragmentation of Bose-Einstein condensates with antiferromagnetic interactions
Luigi De Sarlo, Lingxuan Shao, Vincent Corre +4
We study spin fragmentation of an antiferromagnetic spin 1 condensate in the presence of a quadratic Zeeman (QZ) effect breaking spin rotational symmetry. We describe how the QZ ef…
Phase diagram of spin 1 antiferromagnetic Bose-Einstein condensates
David Jacob, Lingxuan Shao, Vincent Corre +5
We study experimentally the equilibrium phase diagram of a spin 1 Bose-Einstein condensate with antiferromagnetic interactions, in a regime where spin and spatial degrees of freedo…
Dynamic generation of spin-squeezed states in bosonic Josephson junctions
B. Juliá-Díaz, T. Zibold, M. K. Oberthaler +3
We analyze the formation of squeezed states in a condensate of ultracold bosonic atoms confined by a double-well potential. The emphasis is set on the dynamical formation of such s…
Atomic homodyne detection of continuous variable entangled twin-atom states
C. Gross, H. Strobel, E. Nicklas +4
Historically, the completeness of quantum theory has been questioned using the concept of bipartite continuous variable entanglement. The non-classical correlations (entanglement)…
Rabi flopping induces spatial demixing dynamics
E. Nicklas, H. Strobel, T. Zibold +4
We experimentally investigate the mixing/demixing dynamics of Bose-Einstein condensates in the presence of a linear coupling between two internal states. The observed amplitude red…

Christian Gross, Tilman Zibold, Eike Nicklas +2
Interference is fundamental to wave dynamics and quantum mechanics. The quantum wave properties of particles are exploited in metrology using atom interferometers, allowing for hig…
Classical bifurcation at the transition from Rabi to Josephson dynamics
Tilman Zibold, Eike Nicklas, Christian Gross +1
We report on the experimental realization of an internal bosonic Josephson junction in a Rubidium spinor Bose-Einstein condensate. The measurement of the full time dynamics in phas…
