Borodin, Alexei; Ferrari, Patrik L. Large time asymptotics of growth models on space-like paths. I: Push ASEP. (English) Zbl 1187.82084 Electron. J. Probab. 13, 1380-1418 (2008). Summary: We consider a new interacting particle system on the one-dimensional lattice that interpolates between TASEP and Toom’s model: A particle cannot jump to the right if the neighboring site is occupied, and when jumping to the left it simply pushes all the neighbors that block its way. We prove that for flat and step initial conditions, the large time fluctuations of the height function of the associated growth model along any space-like path are described by the \(\text{Airy}_1\) and \(\text{Airy}_2\) processes. This includes fluctuations of the height profile for a fixed time and fluctuations of a tagged particle’s trajectory as special cases.
