Dynamical theory of icosahedral order parameter in supercooled liquids

Kawasaki, Kyozi - In: Physica A: Statistical Mechanics and its Applications 246 (1997) 1, pp. 64-74

An attempt is made to incorporate icosahedral order believed to be present in supercooled liquids into a dynamical theory. We use the representation of Nelson et al., where the physical density is obtained by sterographic projection of hypersphere. Self-consistent mode-coupling equation is...

Analysis of decoupling of DC conductivity and structural relaxation time in epoxies with different molecular topology

Psurek, T.; Ziolo, J.; Paluch, M. - In: Physica A: Statistical Mechanics and its Applications 331 (2004) 3, pp. 353-364

and temperature pathways. The phenomenon of decoupling between the DC-conductivity and the structural (α-) relaxation time … pressure independent, and its value can be determined from the ratio of activation volumes for the DC-conductivity relaxation … and the structural relaxation process, respectively. The results for MBDGA have been compared with results previously …
