Sound propagation in a Bose-Einstein condensate at finite temperatures
R. Meppelink, S. B. Koller, P. van der Straten
We study the propagation of a density wave in a magnetically trapped Bose-Einstein condensate at finite temperatures. The thermal cloud is in the hydrodynamic regime and the system…
Atom lithography without laser cooling
B. Smeets, P. van der Straten, T. Meijer +2
Using direct-write atom lithography, Fe nanolines are deposited with a pitch of 186 nm, a full width at half maximum (FWHM) of 50 nm, and a height of up to 6 nm. These values are a…
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…
