Solitones Disipativos, su asimetría y su uso como trinquetes de un motor browniano autónomo

Resumen

Solitonic wave-mediated transport is shown to be possible for a class of anharmonic lattice problems where due to wave asymmetry the wave can be used as a traveling periodic ratchet, thus defining a kind of autonomous Brownian motor. Using a (mesoscopic) probabilistic description we have assessed the role of both viscous friction and temperature in both the direction of transport and its quantitative features. No asymmetry is required on the potential. Furthermore its actual form and even that of the periodic wave, save its asymmetry, play no significant role in the results obtained and hence the latter are of rather universal value
