Abstract
Abstract
We study a periodic system of interacting particles, such as TASEP, Push, or PushASEP. The observable of interest is the cumulative current at a given location, which counts the algebraic number of particle jumps to the right (+1) and to the left (-1). Applying the Bethe ansatz and the contour integral approach, the limiting distribution of this observable at the relaxation time-scale can be established, which is also known as the one-point distribution of the periodic KPZ fixed point. One interesting feature of this limiting distribution is that it interpolates the Gaussian distribution and the Tracy--Widom distribution.
