Integrability of the multi-species ASEP with long-range jumps on $\mathbb{Z}$
Abstract
Let us consider a two-sided multi-species stochastic particle model with finitely many particles on defined as follows. Suppose that each particle is labelled by a positive integer and waits a random time exponentially distributed with rate . It then chooses the right direction to jump with probability or the left direction with probability . If the particle chooses the right direction, it jumps to the nearest site occupied by a particle (with the convention that an empty site is considered as a particle with labelled ). If the particle chooses the left direction, it follows the rule of the multi-species totally asymmetric simple exclusion process (mTASEP). We show that this model is integrable and provide the exact formula of the transition probability using the Bethe ansatz.
