Speeding chemical reactions by focusing
A. M. Lacasta, L. Ramirez-Piscina, J. M. Sancho +1
We present numerical results for a chemical reaction of colloidal particles which are transported by a laminar fluid and are focused by periodic obstacles in such a way that the tw…
Weak disorder: anomalous transport and diffusion are normal yet again
M. Khoury, A. M. Lacasta, J. M. Sancho +1
Particles driven through a periodic potential by an external constant force are known to exhibit a pronounced peak of the diffusion around a critical force that defines the transit…
Controlling Chaotic transport on Periodic Surfaces
R. Chacon, A. M. Lacasta
We uncover and characterize different chaotic transport scenarios on perfect periodic surfaces by controlling the chaotic dynamics of particles subjected to periodic external force…
Dispersionless transport in a washboard potential
Katja Lindenberg, J. M. Sancho, A. M. Lacasta +1
We study and characterize a new dynamical regime of underdamped particles in a tilted washboard potential. We find that for small friction in a finite range of forces the particles…
Dynamics of an inchworm nano-walker
A. Ciudad, J. M. Sancho, A. M. Lacasta
An inchworm processive mechanism is proposed to explain the motion of dimeric molecular motors such as kinesin. We present here preliminary results for this mechanism focusing on o…
An analytical approach to sorting in periodic potentials
James P. Gleeson, J. M. Sancho, A. M. Lacasta +1
There has been a recent revolution in the ability to manipulate micrometer-sized objects on surfaces patterned by traps or obstacles of controllable configurations and shapes. One…
