Dynamic Order-Disorder in Atomistic Models of Structural Glass Formers
TLDR
Numerical evidence is presented for the existence of a novel first-order dynamical phase transition in atomistic models of structural glass formers, offering the possibility of a unified picture of glassy phenomena.

Large deviations and ensembles of trajectories in stochastic models
We consider ensembles of trajectories associated with large deviations of time-integrated quantities in stochastic models. Motivated by proposals that these ensembles are relevant for physical…

Ergodicity and large deviations in physical systems with stochastic dynamics
Abstract In ergodic physical systems, time-averaged quantities converge (for large times) to their ensemble-averaged values. Large deviation theory describes rare events where these time averages…

Overview of different characterisations of dynamic heterogeneity
TLDR
This work describes how initial, indirect observations of dynamic heterogeneity have recently evolved into well-defined, quantitative, statistical characterisations, in particular through the use of high-order correlation and response functions.

Dynamical first-order phase transition in kinetically constrained models of glasses.
We show that the dynamics of kinetically constrained models of glass formers takes place at a first-order coexistence line between active and inactive dynamical phases. We prove this by computing the…

Population-dynamics method with a multicanonical feedback control.
TLDR
This work discusses the Giardinà-Kurchan-Peliti population dynamics method for evaluating large deviations of time-averaged quantities in Markov processes, and demonstrates substantially improved results in a simple model.

Hyperuniformity and phase separation in biased ensembles of trajectories for diffusive systems.
TLDR
This work uses fluctuating hydrodynamics to show that biased ensembles of trajectories for diffusive systems exhibit phase transitions into "hyperuniform" states, where large-wavelength density fluctuations are strongly suppressed.

Fluctuation-dissipation ratios in the dynamics of self-assembly.
TLDR
This work considers two seemingly very different self-assembly processes: formation of viral capsids and crystallization of sticky disks, and shows that fluctuation-dissipation ratios are a useful indicator of the long-term fate of the system, based on the early stages of assembly.

The phosphate deposits of South Australia
Evidence for a Disordered Critical Point in a Glass-Forming Liquid.
TLDR
It is argued that this critical point directly reveals the existence of an interfacial tension between amorphous metastable states, a quantity relevant both for equilibrium relaxation and for nonequilibrium melting of stable glass configurations.
