F. Roshani et M. Khorrami, Asymmetric one-dimensional exclusion processes: A two-parameter exactly solvable example, PHYS REV E, 60(3), 1999, pp. 3393-3395
We consider a two-parameter family of asymmetric exclusion processes for pa
rticles living on a continuous one-dimensional space. Using the Bethe ansat
z, the exact solution to the master equation, and from that the drift and t
he diffusion rate in the two particle sector, are obtained. [S1063-651X(99)
