Revealing hidden structural order controlling both fast and slow glassy dynamics in supercooled liquids
The dynamics of a supercooled liquid near the glass transition is characterized by two-step
relaxation, fast β and slow α relaxations. Because of the apparently disordered nature of …

Disordered collective motion in dense assemblies of persistent particles
We explore the emergence of nonequilibrium collective motion in disordered nonthermal
active matter when persistent motion and crowding effects compete, using simulations of a …

Long-wavelength fluctuations and the glass transition in two dimensions and three dimensions
Phase transitions significantly differ between 2D and 3D systems, but the influence of
dimensionality on the glass transition is unresolved. We use microscopy to study colloidal …
