Query: Power-Law Stretching of Associating Polymers in Steady-State Extensional
  Flow   We present a tube model for the Brownian dynamics of associating polymers in
extensional flow. In linear response, the model confirms the analytical
predictions for the sticky diffusivity by Leibler- Rubinstein-Colby theory.
Although a single-mode DEMG approximation accurately describes the transient
stretching of the polymers above a 'sticky' Weissenberg number (product of the
strain rate with the sticky-Rouse time), the pre-averaged model fails to
capture a remarkable development of a power-law distribution of stretch in
steady-state extensional flow: while the mean stretch is finite, the
fluctuations in stretch may diverge. We present an analytical model that shows
how strong stochastic forcing drive the long tail of the distribution, gives
rise to rare events of reaching a threshold stretch and constitutes a framework
within which nucleation rates of flow-induced crystallization may understood in
systems of associating polymers under flow. The model also exemplifies a wide
class of driven systems possessing strong, and scaling, fluctuations.
