Abstract
The relationship between extended structures, glassy dynamics and an
underlying critical point is examined in the context of a lattice
model of fluctuating lines. Monte Carlo simulations are used to
construct an effective, coarse-grained dynamics for the "order
parameter" near the critical point. Analysis of the effective
dynamics reveals that the critical point is associated with diverging
barriers leading to the observed Vogel-Fulcher divergence of the
relaxation times. A direct connection is established between the
presence of extended structures and the activated dynamics.
