Collective oscillations of a classical gas confined in harmonic traps
D. Guery-Odelin, F. Zambelli, J. Dalibard +1
Starting from the Boltzmann equation we calculate the frequency and the damping of the monopole and quadrupole oscillations of a classical gas confined in an harmonic potential. Th…
Hydrodynamic modes in a trapped Bose gas above the Bose-Einstein transition
A. Griffin, Wen-Chin Wu, S. Stringari
We discuss the collective modes of a trapped Bose gas in the hydrodynamic regime where atomic collisions ensure local thermal equilibrium for the distribution function. Starting fr…
The Surface Region of Superfluid He as a Dilute Bose-Condensed Gas
A. Griffin, S. Stringari
In the low-density surface region of superfluid He, the atoms are far apart and collisions can be ignored. The only effect of the interactions is from the long-range attractive…
Surface Region of Superfluid Helium as an Inhomogeneous Bose-Condensed Gas
A. Griffin, S. Stringari
We present arguments that the low density surface region of self-bounded superfluid He systems is an inhomogeneous dilute Bose gas, with almost all of the atoms occupying the s…
