Bogoliubov excitation spectrum in anharmonic traps
E Gershnabel, N Katz, E Rowen +1
We study the linearized Bogoliubov excitation spectrum of infinitely long anharmonically trapped Bose-Einstein condensates, with the aim of overcoming inhomogeneous broadening. We…
Splitting in the Excitation Spectrum of A Bose-Einstein Condensate Undergoing Strong Rabi Oscillations
E. Rowen, R. Ozeri, N. Katz +2
We report on a measurement of splitting in the excitation spectrum of a condensate driven by an optical travelling wave. Experimental results are compared to a numerical solution o…
Decoherence and dephasing in strongly driven colliding Bose-Einstein condensates
N. Katz, R. Ozeri, E. Rowen +2
We report on a series of measurements of decoherence and wavepacket dephasing between two colliding, strongly coupled, identical Bose-Einstein condensates. We measure, in the stron…
Bragg spectroscopy of the multi-branch Bogoliubov spectrum of elongated Bose-Einstein condensates
J. Steinhauer, N. Katz, R. Ozeri +3
We measure the response of an elongated Bose-Einstein condensate to a two-photon Bragg pulse. If the duration of the pulse is long, the total momentum transferred to the condensate…
Three-wave mixing of Bogoliubov quasi-particles in a Bose condensate
R. Ozeri, N. Katz, J. Steinhauer +1
A dressed basis is used to calculate the dynamics of three-wave mixing between Bogoliubov quasi-particles in a Bose condensate. Due to the observed oscillations between different m…
Beliaev damping of quasi-particles in a Bose-Einstein condensate
N. Katz, J. Steinhauer, R. Ozeri +1
We report a measurement of the suppression of collisions of quasi-particles with ground state atoms within a Bose-Einstein condensate at low momentum. These collisions correspond t…
