Scaling of configurational entropy with activity

Characterize the scaling behavior of the configurational entropy change of the tangentially driven active Brownian polymer as a function of the Péclet number.

Background

The paper applies entropy estimates from stochastic interpolants to a nonequilibrium tangentially active Brownian polymer whose activity is measured by the Péclet number. The reported results show that activity above a Péclet number of approximately one substantially reduces the polymer’s configurational entropy relative to the passive reference ensemble. However, the authors state that the functional scaling of this entropy change with activity cannot yet be identified, leaving the dependence on the Péclet number unresolved for future investigation.
