On integrability of zero-range chipping models with factorized steady state

Understand

Conditions of integrability of general zero range chipping models with factorized steady state, which were proposed in [Evans, Majumdar, Zia 2004 J.

• Phys.
• A 37 L275], are examined.
• We find a three-parametric family of hopping probabilities for the models solvable by the Bethe ansatz, which includes most of known integrable stochastic particle models as limiting cases.
