Description

I will discuss the long time asymptotic behavior of a tagged particle in two dimensional systems, where the particles are stuck with their neighbors. This corresponds to single-file diffusion in one dimension, where the mean squared displacement of a particle grows with the square root of time. In two dimensions it turns out that the mean square displacement grows logarithmically. I will show how one can arrive at these results through an approach called harmonization.
