Fluctuations in the Time Variable and Dynamical Heterogeneity in Glass-Forming Systems
Karina E. Avila, Horacio E. Castillo, Azita Parsaeian
We test a hypothesis for the origin of dynamical heterogeneity in slowly relaxing systems, namely that it emerges from soft (Goldstone) modes associated with a broken continuous sy…
Fluctuating Phases and Fluctuating Relaxation Times in Glass Forming Liquids
Gcina A. Mavimbela, Azita Parsaeian, Horacio E. Castillo
The presence of fluctuating local relaxation times, has been used for some time as a conceptual tool to describe dynamical heterogeneities in glass-forming systems. Howeve…
Mapping dynamical heterogeneity in structural glasses to correlated fluctuations of the time variables
Karina E. Avila, Horacio E. Castillo, Azita Parsaeian
Dynamical heterogeneities -- strong fluctuations near the glass transition -- are believed to be crucial to explain much of the glass transition phenomenology. One possible hypothe…
Universal fluctuations in the relaxation of structural glasses
Azita Parsaeian, Horacio E. Castillo
The presence of strong local fluctuations -- dynamical heterogeneities -- has been observed near the glass transitions of a wide variety of materials. Here we explore the possible…
Equilibrium and non-equilibrium fluctuations in a glass-forming liquid
Azita Parsaeian, Horacio E. Castillo
Glass-forming liquids display strong fluctuations -- dynamical heterogeneities -- near their glass transition. By numerically simulating a binary Weeks-Chandler-Andersen liquid and…
Local fluctuations in the aging of a simple glass
Horacio E. Castillo, Azita Parsaeian
The presence of dynamical heterogeneities, i.e. nanometer-scale regions containing molecules rearranging cooperatively at very different rates compared to the bulk, is increasingly…
Growth of spatial correlations in the aging of a simple structural glass
Azita Parsaeian, Horacio E. Castillo
We present a detailed numerical study of dynamical heterogeneities in the aging regime of a simple binary Lennard-Jones glass former. For most waiting times t_w and final times t,…
