Entanglement Entropy and Mutual Information Production Rates in Acoustic Black Holes
Stefano Giovanazzi
A method to investigate acoustic Hawking radiation is proposed, where entanglement entropy and mutual information are measured from the fluctuations of the number of particles. The…
Gravity-analogy in one-dimensional ideal Fermi fluids and Burgers' equation
Stefano Giovanazzi
An hydrodynamic description of a one-dimensional flow of an ideal Fermi fluid is constructed from a semiclassical approximation. For an initially fully degenerate fluid, Euler and…
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…
