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 ...
Thermo-mechanical ratcheting in soil–structure interfaces
(Springer Verlag, 2019)
© 2019, Springer-Verlag GmbH Germany, part of Springer Nature.This paper proposes and validates a thermo-mechanical ratcheting mechanism that explains the cumulative displacement of soil–continuum interfaces when subjected ...
A new formulation of heat dissipation in a rocking Büttiker-Landauer ratchet model
(Elsevier, 2019-10)
Thermal ratchets achieve net particle transport through recti cation of thermal uctuations, which arise from one or more heat baths in the system. We propose a new formulation of heat dissipation from the ratchet to the ...
Transient superdiffusive motion on a disordered ratchet potential
(Elsevier Science, 2019-06)
The relationship between anomalous superdiffusive behavior and particle trapping probability is analyzed on a rocking ratchet potential with spatially correlated weak disorder. The trapping probability density is shown, ...
Thermo-mechanical ratcheting in jointed rock masses
(ICE Pub., 2015)
Thermo-mechanical coupling takes place in jointed rock masses subjected to large thermal oscillations. Examples range from exposed surfaces under daily and seasonal thermal fluctuations to subsurface rock masses affected ...
Fluctuation-induced transport: From the very small to the very large scales
(Papers in Physics, 2016-02)
The study of fluctuation-induced transport is concerned with the directed motion of particles on a substrate when subjected to a fluctuating external field. Work over the last two decades provides now precise clues on how ...
