We consider the atom-optical delta-kicked accelerator when the initial momentum distribution is symmetric. We demonstrate the existence of quantum-resonant dynamics, and derive analytic expressions for the system evolution. In particular, we consider...

Bright solitary-matter-wave collisions in a harmonic trap: Regimes of solitonlike behavior (2008)
Journal Article

Systems of solitary waves in the one-dimensional Gross-Pitaevskii equation, which models a trapped atomic Bose-Einstein condensate, are investigated theoretically. To analyze the soliton nature of these solitary waves, a particle analogy for the soli... Read More about Bright solitary-matter-wave collisions in a harmonic trap: Regimes of solitonlike behavior.
