Description |
A spatially extended system often involves a large number of degrees of freedom that are strongly interacting with one another. Here, we analyze the dynamics of a tagged monomer of an elastic chain of polymers. In the case of free evolution, the monomer displays subdiffusive behavior. In presence of a quench/resetting protocol, our exact solution shows that the system displays strong memory-dependent relaxation and nontrivial out-of-equilibrium steady states.
