Is there a higher-order Mode Coupling transition in polymer blends?
Angel J. Moreno, Juan Colmenero
We present simulations on a binary blend of bead-spring polymer chains. The introduction of monomer size disparity yields very different relaxation times for each component of the…
Neutron scattering investigations on methyl group dynamics in polymers
Juan Colmenero, Angel J. Moreno, Angel Alegria
Among the different dynamical processes that take place in polymers, methyl group rotation is perhaps the simplest one, since all the relevant interactions on the methyl group can…
Dynamics in a supercooled liquid of symmetric dumbbells: Reorientational hopping for small molecular elongations
Angel J. Moreno, Song-Ho Chong, Walter Kob +1
We present extensive molecular dynamics simulations of a liquid of symmetric dumbbells, for constant packing fraction, as a function of temperature and molecular elongation. For la…
Evidence for the weak steric hindrance scenario in the supercooled-state reorientational dynamics
S. -H. Chong, A. J. Moreno, F. Sciortino +1
We use molecular-dynamics computer simulations to study the translational and reorientational dynamics of a glass-forming liquid of dumbbells. For sufficiently elongated molecules…
