Observation of harmonic generation and nonlinear coupling in the collective dynamics of a bose-einstein condensate.
Phys Rev Lett 85:4 (2000) 692-695
Abstract:
We report the observation of harmonic generation and strong nonlinear coupling of two collective modes of a condensed gas of rubidium atoms. Using a modified time averaged orbiting potential trap we changed the trap anisotropy to a value where the frequency of the m = 0 high-lying mode corresponds to twice the frequency of the m = 0 low-lying mode, thus leading to strong nonlinear coupling between these modes. By changing the anisotropy of the trap and exciting the low-lying mode we observed significant frequency shifts of this fundamental mode and also the generation of its second harmonic.Measurement of the W Boson Mass with the Collider Detector at Fermilab
