Beyond mean field effects in the high momentum energy spectrum of a Bose gas: revisiting Beliaev's theory
Shai Ronen
The well-known Bogoliubov expression for the spectrum of a weakly interacting dilute Bose gas becomes inadequate when the density or interactions strength are increased. The correc…

Dynamical pattern formation during growth of a dual-species Bose-Einstein condensate
Shai Ronen, John L. Bohn, Laura E. Halmo +1
We simulate the growth of a dual species Bose-Einstein condensate using a Gross-Pitaevskii equation with an additional gain term giving rise to the growth. Such growth occurs durin…

Bragg spectroscopy of a strongly interacting 85Rb Bose-Einstein condensate
S. B. Papp, J. M. Pino, R. J. Wild +4
We report on measurements of the excitation spectrum of a strongly interacting Bose-Einstein condensate (BEC). A magnetic-field Feshbach resonance is used to tune atom-atom interac…
