We study the effect of intercomponent interactions on the dynamical properties of quantum walkers. We consider the simplest situation of two indistinguishable noninteracting walkers on a tilted optical lattice interacting with a walker from a different component. The mediated effect of the third particle is then analyzed in the backdrop of various controlling parameters. The interaction-induced two-particle correlations are shown to be nontrivially affected by the particle statistics, choice of initial states, and tilt configurations of the lattice. Our analysis thus offers an overall picture and serves as a starting point of a study of interacting multicomponent quantum walkers.
