  We numerically study the escape kinetics of a self-propelled Janus particle,
carrying a cargo, from a meta-stable state. We assume that the cargo is
attached to the Janus particle by a flexible harmonic spring. We take into
account the effect of velocity field, created in the fluid due to movements of
dimer's components, by considering space-dependent diffusion tensor (Oseen
tensor). Our simulation results show that the synchronization between barrier
crossing events and rotational relaxation process can enhance escape rate to a
large extent. Also, the load carrying capability of a Janus particle is largely
controlled by its rotational dynamics and self-propulsion velocity. Moreover,
the hydrodynamic interaction, conspicuously, enhances the escape rate of the
Janus-cargo dimer. The most of the important features in escape kinetics have
been justified based on the analytic arguments.
