Periodic ASEP and random walks on affine Hecke Algebra

Alexey Bufetov, Nimisha Pahuja

We study the large time behavior of a periodic ASEP with fixed period started from the step initial condition. We establish the limit shape theorem and the asymptotic distribution…

Mallows Product Measure

Alexey Bufetov, Kailun Chen

Q-exchangeable ergodic distributions on the infinite symmetric group were classified by Gnedin-Olshanski (2012). In this paper, we study a specific linear combination of the ergodi…

Interacting particle systems and random walks on Hecke algebras

Alexey Bufetov

In this paper we show that a variety of interacting particle systems with multiple species can be viewed as random walks on Hecke algebras. This class of systems includes the asymm…

Shock fluctuations in TASEP under a variety of time scalings

Alexey Bufetov, Patrik L. Ferrari

We consider the totally asymmetric simple exclusion process (TASEP) with two different initial conditions with shock discontinuities formed by blocks of fully packed particles. Ini…
