SmoothRough Phase Transitions in Deposition Processes with a Heat Flow and an Electrical Current.
Abstract
We study a simple multiple flow particle deposition system where a brownian conducting particle is exposed to both a heat flow and a constant electrical current through the system. We calculate the steadystate probability density for the position of the particle as a function of the relative strengths of the two flows. We find a phase transition between smooth and ramified patterns where critical heat flow scales almost linearly as a function of the current. We discuss possible applications to batteries.
