Query: Cluster Glasses of Semiflexible Ring Polymers   We present computer simulations of concentrated solutions of unknotted
nonconcatenated semiflexible ring polymers. Unlike in their flexible
counterparts, shrinking involves a strong energetic penalty, favoring
interpenetration and clustering of the rings. We investigate the slow dynamics
of the centers-of-mass of the rings in the amorphous cluster phase, consisting
of disordered columns of oblate rings penetrated by bundles of prolate ones.
Scattering functions reveal a striking decoupling of self- and collective
motions. Correlations between centers-of-mass exhibit slow relaxation, as
expected for an incipient glass transition, indicating the dynamic arrest of
the cluster positions. However, self-correlations decay at much shorter time
scales. This feature is a manifestation of the fast, continuous exchange and
diffusion of the individual rings over the matrix of clusters. Our results
reveal a novel scenario of glass-formation in a simple monodisperse system,
characterized by self-collective decoupling, soft caging and mild dynamic
heterogeneity.
