Popis:	The dynamics of the coexisting ultracold atomic and molecular condensates in the presence of Feshbach resonance, atom–atom, molecule–molecule and atom–molecule interactions is described in terms of coupled Gross–Pitaevskii equation. We show that the appearence of oscillation or the existence of Josephson-like currents in the condensates is the natural consequence of the Gross–Pitaevskii equation under a suitable approximation regarding the nature of the condensate wave function.
