Coherent, Adiabatic and Dissociation Regimes in Coupled Atomic-Molecular Bose-Einstein Condensates

Published

Author(s)

Abstract

We discuss the dynamics of a Bose-Einstein condensate of atoms suddenly coupled to a condensate of molecules by an optical or magnetic Feshbach resonance. Three limiting regimes are found and can be understood from the transient dynamics occuring for each pair of atoms. This transient dynamics can be summarised into a time-dependent shift and broadening of the molecular state. A simple Gross-Pitaevskii picture including this shift and broadening is proposed to describe the system in the three regimes. Finally, we suggest how to explore these regimes experimentally.
