Query: Stabilization of ratchet dynamics by weak periodic signals   We study the influence of weak periodic signals on the transport properties
of underdamped ratchets. We find that the constant current intervals related to
the ratchet, can be significantly enlarged by a weak subharmonic signal which
is in phase with the internal driver. This stabilization phenomenon is found to
exist both in absence and in presence of noise. The dependence of this effect
on the phase of the applied signal is also investigated.
