While the interacting active particles are well studied in the large (hydrodynamics) scale, deciphering properties at the small scale remains largely open. A systematic and rigorous analytic treatment for the non-equilibrium statistical mechanics of multiple active particles has still been lacking. In this talk, I will demonstrate a simple setting of harmonic chain where many properties can be analytically computed. Primary focus will be on the statistical properties of the tagged particle's position x(t) for three active particle dynamics - run and tumble model, active Brownian particle and active Ornstein Uhlenbeck particle. Various cross-over behaviours for the correlations and fluctuations of x(t), previously conjectured, will be explicitly derived.
