Squeezing and entanglement in a Bose-Einstein condensate
J. Esteve, C. Gross, A. Weller +2
Entanglement, a key feature of quantum mechanics, is a resource that allows the improvement of precision measurements beyond the conventional bound reachable by classical means. Th…
Strong dipolar effects in a quantum ferrofluid
Thierry Lahaye, Tobias Koch, Bernd Froehlich +5
We report on the realization of a Chromium Bose-Einstein condensate (BEC) with strong dipolar interaction. By using a Feshbach resonance, we reduce the usual isotropic contact inte…
Collective oscillations of dipolar Bose-Einstein condensates and accurate comparison between contact and dipolar interaction
S. Giovanazzi, L. Santos, T. Pfau
We propose a scheme for the measurement of the s-wave scattering length of an atom or molecule with significant dipole-dipole interaction with an accuracy at the percent level.…
Comparing contact and dipolar interaction in a Bose-Einstein condensate
Axel Griesmaier, Jürgen Stuhler, Tobias Koch +3
We have measured the relative strength of the magnetic dipole-dipole interaction compared to the contact interaction in a chromium Bose-Einstein condensate. We analyze the a…
Expansion dynamics of a dipolar Bose-Einstein condensate
S. Giovanazzi, P. Pedri, L. Santos +5
Our recent measurements on the expansion of a chromium dipolar condensate after release from an optical trapping potential are in good agreement with an exact solution of the hydro…
The sonic analogue of black hole radiation
S. Giovanazzi
A microscopic description of Hawking radiation in sonic black holes has been recently presented (Giovanazzi S 2005 Phys. Rev. Lett. 94 061302). This exactly solvable model is formu…
