Hydrodynamic modes and pulse propagation in a cylindrical Bose gas above the Bose-Einstein transition
We study hydrodynamic oscillations of a cylindrical Bose gas above the BoseEinstein transition temperature using the hydrodynamic equations derived by Griffin, Wu and Stringari. This extends recent studies of a cylindrical Bosecondensed gas at T = 0. Explicit normal mode solutions are obtained for nonpropagating solutions. In the classical limit, the sound velocity is shown to be the same as a ...
متن کاملChaos in collapsing Bose-condensed gas
We reinvestigate the dynamics of the grow and collapse of Bose-Einstein condensates in a system of trapped ultracold atoms with negative scattering lengths, and found a new behavior in the long time scale evolution: the number of atoms can go far beyond the static stability limit. The condensed state is described by the solution of the time-dependent nonlinear Schrödinger equation, in a model t...
متن کاملObservation of superfluid flow in a bose-einstein condensed Gas
We have studied the hydrodynamic flow in a Bose-Einstein condensate stirred by a macroscopic object, a blue-detuned laser beam, using nondestructive in situ phase contrast imaging. A critical velocity for the onset of a pressure gradient has been observed, and shown to be density dependent. The technique has been compared to a calorimetric method used previously to measure the heating induced b...
متن کاملCalorimetry of a Bose–Einstein-condensed photon gas
Phase transitions, as the condensation of a gas to a liquid, are often revealed by a discontinuous behaviour of thermodynamic quantities. For liquid helium, for example, a divergence of the specific heat signals the transition from the normal fluid to the superfluid state. Apart from liquid helium, determining the specific heat of a Bose gas has proven to be a challenging task, for example, for...
متن کاملCollective Excitations of a Trapped Bose-Condensed Gas.
By taking the hydrodynamic limit we derive, at T = 0, an explicit solution of the linearized time dependent Gross-Pitaevskii equation for the order parameter of a Bose gas confined in a harmonic trap and interacting with repulsive forces. The dispersion law ω = ω0(2n 2 + 2nl+ 3n + l)1/2 for the elementary excitations is obtained, to be compared with the prediction ω = ω0(2n+ l) of the nonintera...
