Noiseless limit of a ferrofluid ratchet
Volker Becker, Andreas Engel
TL;DR
This paper demonstrates that in a ferrofluid-based thermal ratchet, directed transport cannot occur without thermal fluctuations, challenging previous claims and clarifying the noiseless limit of such systems.
Contribution
It provides a rigorous proof that no directed transport occurs in the noiseless limit of ferrofluid ratchets, correcting prior assumptions.
Findings
Directed transport is absent in the noiseless limit.
Thermal fluctuations are essential for ratchet operation.
Previous claims of noiseless directed transport are invalid.
Abstract
The noiseless limit of a thermal ratchet device using ferrofluids is studied in detail. Contrary to previous claims it is proved that no directed transport can occur in this model in the absence of fluctuations.
