Ballistic coalescence model

Abstract: We study statistical properties of a one-dimensional infinite system of interacting particles. Each particle moves with constant velocity towards its closest neighbor and particles coalesce upon collisions. We propose a mean-field theory that predicts a t−1 concentration decay, confirmed by simulations, and provides qualitative description for the densities of growing, constant, and shrinking inter-particle gaps.
