Dynamics of a single polymer chain in Gaussian and non-Gaussian active baths

In this talk, we intend to give an overview of the structure and dynamics of a single polymer chain in active baths, Gaussian or non-Gaussian. We consider a single flexible or semiflexible linear polymer chain subjected to two noises, thermal and active. The active noise has either Gaussian [1] or non-Gaussian [2] distribution but has a memory, accounting for the persistent motion of the active bath particles. This finite persistence makes the reconfiguration dynamics of the chain slow as compared to the purely thermal case and the chain swells. The active noise also results in superdiffusive or ballistic motion of the tagged monomer. In addition, we point out the relevance of polymer chains in active baths in biologically relevant contexts [3].
