A system composed of filament-like bead-spring polymer chains can stay at a temperature-varying non-equilibrium “quasi-steady” situation [1], in which the velocity distribution of monomers is described by a generalized Maxwell-Boltzmann distribution, which is in the form of Tsallis q-Gaussian [2] with a fixed value for q. In this study, we carried out a detailed examination on the effects of anisotropy along the backbones of the chains on the dynamics of the monomers, which underscore a scenario of non-ergodic thermal equilibration for mechanically dynamic-balanced systems.
