Abstract

A zero-temperature collisionless dynamics of a two-species degenerate atomic Fermi gas was investigated near a Feshbach resonance. The main objective for the investigation was to understand the evolution of the system following a nonadiabatic change in an externally-controlled system's parameter. It was found that the resulting solitonlike collisionless dynamics can be calculated analytically in the narrow resonance limit. The results show that the amplitude of the atom-molecule oscillations disappears as the molecular energy approaches zero.
