A relation between the diffusion coefficient D and the distance λ that a particle can jump when diffusing in a time τ. The Einstein-Smoluchowski equation, which is D = λ2/2τ, gives a connection between the microscopic details of particle diffusion and the macroscopic quantities associated with the diffusion, such as the viscosity In the literature the Einstein-Smoluchowski equation is called the Kolmogorov-Chapman equation. The physical analysis of a process of Brownian-motion type shows that it can be described by means of the function $ P $ on intervals $ \Delta t = t - t _ {0} $ considerably larger than the correlation time of the stochastic process (even if $ \Delta t \rightarrow 0 $ formally), and that the moment ** Thus the Einstein-Smoluchowski relation results into the Stokes-Einstein relation D = k B T 6 π η r **. {\displaystyle D={\frac {k_{\text{B}}T}{6\pi \,\eta \,r}}.} This has been applied for many years to estimating the self-diffusion coefficient in liquids, and a version consistent with isomorph theory has been confirmed by computer simulations of the Lennard-Jones system Keywords: Einstein, Smoluchowski, Langevin equation, Stokes-Einstein, rotation, fluctuation, viscosity, root-mean-square displacement, random force, friction Oxford Scholarship Online requires a subscription or purchase to access the full text of books within the service

Einstein and Smoluchowski's treatment of the Brownian motion has been discussed. It is shown that although the diffusion equations derived from both treatments are mathematically identical, Smoluchowski's equation defines a somewhat concentration-dependent diffusion coefficient, while Einstein's equation defines a constant diffusion coefficient * A third way to calculate the diffusion concentration is through the Einstein-Smoluchowski equation: \[ D = \dfrac{\lambda^2}{2\tau} \label{4} \] where \(λ\) is the length that each step takes, and \(τ\) is the time that each step takes*. In this particular model, each step is the same distance Appendix A Up: Stochastic processes Previous: The Smoluchowski time scale The Smoluchowski equation.

Physica A: Statistical Mechanics and its Applications, 1992, vol. 180, issue 3, 336-358 . Abstract: Beginning from the specific model of the Boltzmann-Peierls equation for the distribution function f(k, t), the time-dependent theory of fluctuations is developed from Einstein's. From these, the Einstein-Smoluchowski and Stokes-Einstein relationships are used to determine the viscosity, which can be directly compared to literature values. The needed trajectories can be calculated in less than 1 h and analyzed in a second hour, leaving a third hour for further explorations as appropriate
