Experimental observation of the Bogoliubov transformation for a Bose-Einstein condensed gas
Abstract
Phonons with wavevector q/\hbar were optically imprinted into a Bose-Einstein condensate. Their momentum distribution was analyzed using Bragg spectroscopy with a high momentum transfer. The wavefunction of the phonons was shown to be a superposition of +q and -q free particle momentum states, in agreement with the Bogoliubov quasiparticle picture.Keywords
