Abstract

I will review the work done with my collaborators on intruders in single-file systems. In such systems, particles are on a one-dimensional line and cannot pass one another. This confinement induces an anomalous dynamics for any given tagged particle (subdiffusion or sub-ballistic motion). Focusing on lattice models (SEP), I will explain how to uncover the underlying structure behind this anomalous dynamics using two methods that we developed. At equilibrium we were able to solve for non-stationary density-displacement corrélations. And for out-of-equilibrium problems at high density, we show that everything is encoded in the random walk of a single vacancy.
