Nonergodic Brownian Motion in a Collinear Particle-Coupled Harmonic Chain Model

We investigate the nonergodic Brownian dynamics in a collinear particle-coupled harmonic chain model, in which the chain is free at one end and fixed at the other end. The behaviors of the particle are mainly studied: the velocity thermalizes faster than the coordinate, and the asymptotic result depends on its initial coordinate preparation which is indeed a kind of the nonergodic behavior.
