Observing atom bunching by the Fourier slice theorem
arXiv:1212.3794 · doi:10.1103/PhysRevLett.110.265301
Abstract
By a novel reciprocal space analysis of the measurement, we report a calibrated in situ observation of the bunching effect in a 3D ultracold gas. The calibrated measurement with no free parameters confirms the role of the exchange symmetry and the Hanbury Brown-Twiss effect in the bunching. Also, the enhanced fluctuations of the bunching effect give a quantitative measure of the increased isothermal compressibility. We use 2D images to probe the 3D gas, using the same principle by which computerized tomography reconstructs a 3D image of a body. The powerful reciprocal space technique presented is applicable to systems with one, two, or three dimensions.
The second version contains additional experimental details. Furthermore, the data is analyzed using two different estimates for the useful area in k-space
