Phase contrast imaging of Bose condensed clouds
R. Meppelink, R. A. Rozendaal, S. B. Koller +2
Phase contrast imaging is used to observe Bose-Einstein condensates (BECs) at finite temperature in situ. The imaging technique is used to accurately derive the absolute phase shif…
Second sound dipole mode in a partially Bose-Einstein condensed gas
R. Meppelink, S. B. Koller, J. M. Vogels +2
We study the second sound dipole mode in a partially Bose-Einstein condensed gas. This mode is excited by spatially separating and releasing the center-of-mass of the Bose-Einstein…
Enhanced heat flow in the hydrodynamic-collisionless regime
R. Meppelink, R. van Rooij, J. M. Vogels +1
We study the heat conduction of a cold, thermal cloud in a highly asymmetric trap. The cloud is axially hydrodynamic, but due to the asymmetric trap radially collisionless. By loca…
Observation of shock waves in a large Bose-Einstein condensate
R. Meppelink, S. B. Koller, J. M. Vogels +6
We observe the formation of shock waves in a Bose-Einstein condensate containing a large number of sodium atoms. The shock wave is initiated with a repulsive, blue-detuned light ba…
Resonant superradiant backward-scattering as a source for many-particle entanglement
K. M. R. van der Stam, R. Meppelink, J. M. Vogels +2
We investigate the atom pair production by superradiant backward-scattering from a Bose-Einstein condensate. By driving the superradiant process with two frequencies we can extend…
Reaching the hydrodynamic regime in a Bose-Einstein condensate by suppression of avalanche
K. M. R. van der Stam, R. Meppelink, J. M. Vogels +1
We report the realization of a Bose-Einstein condensate (BEC) in the hydrodynamic regime. The hydrodynamic regime is reached by evaporative cooling at a relative low density suppre…
