A short-time quantum mechanical expansion approach to vibrational relaxation

Article Abstract:

A study was conducted to investigate the possibility of calculating the quantum mechanical vibrational relaxation rate from a quantum Taylor expansion of the force-force correlation function. The relaxation rate was formulated within the lowest order perturbation theory combined with the Kubo transform of the force-force correlation function.

Diffusion and the mesoscopic hydrodynamics of supercooled liquids

Article Abstract:

The mosaic picture of the supercooled liquids based on the random first-order transition theory was examined. The unusual decoupling of translational diffusion from the macroscopic hydrodynamics of glass-forming liquids is observed.
