Query: Logarithmic coarsening and glassy behavior in a polymer model with
  mass-dependent diffusion   We present a model of polymer growth and diffusion with frustration
mechanisms for density increase and with diffusion rates of Arrhenius form with
mass-dependent energy barriers Gamma(m) ~ (m-1)^gamma. It shows non-universal
logarithmic coarsening involving the exponent gamma. Strong-glass behavior is
found in the typical times for disappearance of all polymers up to a given
length, without reference to the equilibrium states of the macroscopic system.
These features are predicted by numerical simulations, scaling theories and an
analytic solution of the master equation within an independent interval
approximation, which also provides the cluster size distribution.
