Interaction-free measurements by quantum Zeno stabilisation of ultracold atoms
J. Peise, B. Lücke, L. Pezzè +6
Quantum mechanics predicts that our physical reality is influenced by events that can potentially happen but factually do not occur. Interaction-free measurements (IFMs) exploit th…
Parametric amplification of vacuum fluctuations in a spinor condensate
C. Klempt, O. Topic, G. Gebreyesus +6
Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplificatio…
Characterization and control of phase fluctuations in elongated Bose-Einstein condensates
H. Kreutzmann, A. Sanpera, L. Santos +7
Quasi one dimensional Bose-Einstein condensates (BECs) in elongated traps exhibit significant phase fluctuations even at very low temperatures. We present recent experimental resul…
Vortex-vortex interactions in toroidally trapped Bose-Einstein condensates
T. Schulte, L. Santos, A. Sanpera +1
We analyze the vortex dynamics and vortex-vortex interactions in Bose-Einstein condensates confined in toroidal traps. We show that this particular geometry strongly distorts the v…
