Impact of rough potentials in rocked ratchet performance
(Elsevier B.V., 2018)
We consider thermal ratchets modeled by overdamped Brownian motion in a spatially periodic potential with a tilting process, both unbiased on average. We investigate the impact of the introduction of roughness in the ...
Optimal Ratcheting of Dividends in a Brownian Risk Model
(2020)
We study the problem of optimal dividend payout from a surplus process governed by Brownian motion with drift under the additional constraint of ratcheting,
i.e. the dividend rate can never decrease. We solve the resulting ...
Induced current in quantum and classical ratchets
(World Scientific, 2010-02)
In a previous work, we described transport in a classical, externally driven, overdamped ratchet. A transport current arises under two possible conditions: either by increasing the external driving or by adding an optimal ...
