Abstract
A series of measurements of decoherence and wave-packet dephasing between two colliding, strongly coupled, identical Bose-Einstein condensates was reported. A suppression of the mean-field shift was measured in the strong-excitation regime. The suppression was explained by applying the Gross-Pitaevskii energy functional. The oscillations for which both inhomogeneous and Doppler broadening were strongly suppressed were observed by selectively counting only the nondecohered fraction in a time-of-flight image. It was observed that collisions can be extracted if no post-selection is used.
