“…More recently, in a series of articles, Baik and Liu investigate the one-point and multi-point distribution of TASEP on the circle of length N , also called periodic TASEP, and obtain the limit function for various initial conditions, including step, flat, and uniformly random initial conditions [3,4,5,6,49]. For a positive density of particles k ≤ N/2, it turns out that a phase transition occurs at a time of order N 3/2 , called the relaxation time scale, where the behavior changes from a Tracy-Widom law to Gaussian fluctuations; see also [7] for a recent relation to the KP equation. Note that this phase transition is in accordance with our results on the mixing time, where we allow for any possible starting configuration.…”
