Srikanth Sastry: „Dynamical heterogeneity, entropy and cooperatively rearranging regions in a model polymer melt”
TIFR Centre for Interdisciplinary Sciences, Hyderabad, India

The relationship between the characteristics of cooperatively rearranging regions leading to structural relaxation, configurational entropy and relaxation times is central to the Adam-Gibbs and random first order transition (RFOT) theories of the glass transition. We examine spatially correlated clusters of mobile, immobile and collectively moving particles, examining their geometry and time scales associated with them, for a model polymer melt. Results from an analysis of these clusters within the framework of the Adam-Gibbs and RFOT theories will be presented.
