The Shapes of Cooperatively Rearranging Regions in Glass Forming Liquids
Jacob D. Stevenson, Joerg Schmalian, Peter G. Wolynes
Abstract
The shapes of cooperatively rearranging regions in glassy liquids change from being compact at low temperatures to fractal or ``stringy'' as the dynamical crossover temperature from activated to collisional transport is approached from below. We present a quantitative microscopic treatment of this change of morphology within the framework of the random first order transition theory of glasses. We predict a correlation of the ratio of the dynamical crossover temperature to the laboratory glass transition temperature, and the heat capacity discontinuity at the glass transition, Delta Cp. The predicted correlation agrees with experimental results for the 21 materials compiled by Novikov and Sokolov.
