The doubly asymmetric simple exclusion process, the colored Boolean process, and the restricted random growth model
Yuhan Jiang
The multispecies asymmetric simple exclusion process (mASEP) is a Markov chain in which particles of different species hop along a one-dimensional lattice. This paper studies the d…
