By considering the master equation of the totally asymmetric exclusion
process on a one-dimensional lattice and using two types of boundary conditions
(i.e. interactions), two new families of the multi-species reactiondiffusion
processes, with particle-dependent hopping rates, are investigated.
In these models (i.e. reaction-diffusion and drop-push systems),
we have the case of distinct particles where each particle A has its own
intrinsic hopping rate v. They also contain the parameters that control
the annihilation-diffusion rates (including pair-annihilation and coagulation
to the right and left). We obtain two distinct new models. It is shown
that these models are exactly solvable in the sense of the Bethe anstaz.
The two-particle conditional probabilities and the large-time behavior of
such systems are also calculated.
