Excitation spectrum of a Bose-Einstein condensate.
We report a measurement of the excitation spectrum omega(k) and the static structure factor S(k) of a Bose-Einstein condensate. The excitation spectrum displays a linear phonon regime, as well as a parabolic single-particle regime. The linear regime provides an upper limit for the superfluid critical velocity, by the Landau criterion. The excitation spectrum agrees well with the Bogoliubov spec...

متن کاملMethod for collective excitation of a Bose-Einstein condensate
Spectacular experimental realizations of the BoseEinstein condensate ~BEC! in cooled and trapped atomic gases @1–3# stimulated intensive investigations of possible modifications, control, and manipulations of this new state of matter. Here a macroscopic sample of atoms is in a well defined quantum state. Thus several typically quantummechanical phenomena may now be investigated on a macroscopic...
متن کاملSimple method for excitation of a Bose-Einstein condensate
Soon after the first spectacular realizations of the BoseEinstein condensate ~BEC! in cooled and trapped atomic gases @1–3#, investigations of possible new effects involving the condensate appeared. The BEC allows us to study several typical quantum-mechanical phenomena on a macroscopic level—because the macroscopic sample of atoms is described by a single wave function. A standard example is t...
متن کاملObservation of shock waves in a large Bose-Einstein condensate
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 barrier, intersecting the BoseEinstein condensate, after which two shock fronts appear. We observe breaking of these waves when the size of these waves approaches the healing length of the condensate. At this time, the w...
