Ultraslow vacancy-mediated tracer diffusion in two dimensions: the Einstein relation verified.
We study the dynamics of a charged tracer particle (TP) on a two-dimensional lattice, all sites of which except one (a vacancy) are filled with identical neutral, hard-core particles. The particles move randomly by exchanging their positions with the vacancy, subject to the hard-core exclusion. In the case when the charged TP experiences a bias due to external electric field E (which favors its...
متن کاملTracer Diffusion in Hard - Core Lattice Gases : Some Notes on the Validity of the Einstein Relation
In this presentation we overview some recent results on biased tracer diffusion in lattice gases. We consider both models in which the gas particles density is explicitly conserved and situations in which the lattice gas particles undergo continuous exchanges with a reservoir, which case is appropriate, e.g., to adsorbed monolayers in contact with the vapor phase. For all these models we determ...
متن کاملContinuum theory of vacancy-mediated diffusion
We present and solve a continuum theory of vacancy-mediated diffusion (as evidenced, for example, in the vacancy driven motion of tracers in crystals). Results are obtained for all spatial dimensions, and reveal the strongly nongaussian nature of the tracer fluctuations. In integer dimensions, our results are in complete agreement with those from previous exact lattice calculations. We also ext...

متن کاملOn the Diffusion Coefficient: The Einstein Relation and Beyond
We present a detailed derivation of the closed-form expression for the diffusion coefficient that was initially obtained by Einstein [4]. The present derivation does not make use of a fictitious force as did the original Einstein derivation, but instead concentrates directly on establishing a dynamic equilibrium between the forces of pressure and friction acting on a Brownian particle. This app...
