Negative Resistance in Brownian Transport

arXiv:cond-mat/0105098 · doi:10.1103/PhysRevLett.76.1968

Abstract

We prove that negative incremental resistance cannot occur on 1D spaces like the circle or the line; we construct an explicit two-dimensional model on the cylinder, and its collapse into a branched 1D backbone. We derive an accurate numerical method for solving our 2D model, and discuss the relevance of the model to biological ion channels.
