Dynamic arrest in a liquid of symmetric dumbbells: Reorientational hopping for small molecular elongations
Dynamic arrest in a liquid of symmetric dumbbells: Reorientational hopping for small molecular elongations
We present extensive equilibrium and out-of-equilibrium molecular-dynamics simulations of a liquid of symmetric dumbbell molecules, for constant packing fraction, as a function of temperature and molecular elongation. We compute diffusion constants as well as odd and even orientational correlators. The notations odd and even refer to the parity of the …
