  In the present work we have studied the dynamics of dipolar atom-molecular
Bose Einstein Condensates coupled via Feshbach Resonance in a double well
potential. We have numerically solved four coupled GP like equations, two for
left well and two for right well for this atom molecular coupled system. Our
numerical results show that both the long-range dipole-dipole interaction
(chosen to be positive) and the coherent coupling interaction (which is
positive for bosons) facilitate the transmission of atoms and molecules from
left well to the right well when the population in the right well dominates
over that in the left well and is trapped for a period of time. Whereas in
absence of any one of these interactions probability of transient transmission
decreases. However in absence of both the interactions (dipole-dipole and
coherent coupling) i.e. when only the repulsive contact interaction is present,
it leads to self trapping in the left well for a period of time. It is also
shown that the signature of coherent coupling between atoms and molecules on
the density distribution of atoms in the double well potential is present both
in absence and presence of dipole-dipole interaction.
