Random Tilings and Markov Chains for Interlacing Particles

We explain the relation between certain random tiling models and interacting particle systems belonging to the anisotropic KPZ (Kardar - Parisi - Zhang) universality class in 2 + 1-dimensions. The link between these two a priori disjoint sets of models is a consequence of the presence of shuffing algorithms that generate random tilings under consideration. To see the precise connection, we represent both a random tiling and the corresponding particle system through a set of non-intersecting lines, whose dynamics is induced by the shuffing algorithm or the particle dynamics. The resulting class of measures on line ensembles also fits into the framework of the Schur processes.
