Intrinsic Ratchets
arXiv:0810.1898 · doi:10.1209/0295-5075/86/30002
Abstract
We present a generic formalism to describe Brownian motion of particles with intrinsic asymmetry and give predictions for the drift behavior in unbiased time-dependent force fields. Our findings are supported by molecular dynamics simulations.
