Figure 1.

Illustration of the inhomogeneous $\ell$-TASEP with open boundaries. Particles (of size $\ell$ = 3 here) enter the first site of the lattice at rate α, and a particle at position i (here denoted by the position of the midpoint of the particle) moves one site to the right at rate p_i, provided that site i + $\ell$ is empty. A particle at the end of the lattice exits at rate β. To see this figure in color, go online.
