Dynamics of a tagged monomer: Effects of elastic pinning and harmonic absorption
arXiv:1308.0284 · doi:10.1103/PhysRevLett.111.210601
Abstract
We study the dynamics of a tagged monomer of a Rouse polymer for different initial configurations. In the case of free evolution, the monomer displays subdiffusive behavior with strong memory of the initial state. In presence of either elastic pinning or harmonic absorption, we show that the steady state is independent of the initial condition which however strongly affects the transient regime, resulting in non-monotonous behavior and power-law relaxation with varying exponents.
