摘要:We consider the totally asymmetric simple exclusion process in a criticalscaling parametrized by a ≥ 0, which creates a shock in the particle density of orderaT−1/3, T the observation time. When at a = 0 one has step initial data, we providebounds on the limiting law of particle positions for a > 0, which in particular implythat in the double limit lima→∞ limT→∞ one recovers the product limit law andthe degeneration of the correlation length observed at shocks of order 1. This resultcan be phrased in terms of a general last passage percolation model. We also obtainbounds on the decoupling of two-point functions of several Airy processes.
