Crossing probabilities in asymmetric exclusion processes | Pablo A. Ferrari

10 Apr 2008 | Abstract: | We consider the one-dimensional asymmetric simple exclusion process in which
particles jump to the right at rate p and to the left at rate 1-p, interacting
by exclusion. Suppose that the initial state has first-class particles to the
left of the origin, a second-class particle at the origin, a third-class
particle at site 1 and holes to the right of site 1. We show that the
probability that the second-class particle overtakes the third-class particle
is (1+p)/3p. We obtain various limiting results about the joint behavior of the
second-class and third-class particles, and a partial extension to a system
with a further (fourth-class) particle. | Source: | arXiv, 0804.1770 | Services: | Forum | Review | PDF | Favorites |
