Realistic extensions of a Brownian ratchet for protein translocation
Dissociation Ratcheting mechanism Cumulative Process
2011/9/21
Abstract: We study a model for the translocation of proteins across membranes through a nanopore using a ratcheting mechanism. When the protein enters the nanopore it diffuses in and out of the pore a...
Ratchet effect on a relativistic particle driven by external forces
Ratchet effect relativistic particle driven
2011/7/6
We study the ratchet effect of a damped relativistic particle driven by both asymmetric temporal bi-harmonic and time-periodic piecewise constant forces. This system can be formally solved for any ex...
Relativistic graphene ratchet on semidisk Galton board

Using extensive Monte Carlo simulations we study numerically and analytically a photogalvanic effect, or ratchet, of directed electron transport induced by a microwave radiation on a semidisk Galton b...
