Cage size and jump precursors in glass-forming liquids: experiment and simulations
Glassy dynamics is intermittent, as particles suddenly jump out of the cage formed by their
neighbors, and heterogeneous, as these jumps are not uniformly distributed across the …

Differential Variance Analysis: a direct method to quantify and visualize dynamic heterogeneities
Many amorphous materials show spatially heterogenous dynamics, as different regions of
the same system relax at different rates. Such a signature, known as Dynamic …

Signature of dynamical heterogeneity in spatial correlations of particle displacement and its temporal evolution in supercooled liquids
I Tah, S Karmakar - Physical Review Research, 2020 - APS
The existence of heterogeneity in the dynamics of supercooled liquids is believed to be one

Activity statistics in a colloidal glass former: experimental evidence for a dynamical transition
In a dense colloidal suspension at a volume fraction below the glass transition, we follow the
trajectories of an assembly of tracers over a large time window. We define a local activity …

Many facets of intermittent dynamics in colloidal and molecular glasses
A popular picture of the intermittent dynamics of glassy materials depicts each particle as
localized in a temporary cage formed by its neighbors, and seldom jumping to another cage …
