We use the "isoconfigurational ensemble" [Phys. Rev. Lett. 93, 135701 (2004)] to analyze both dynamical and structural properties in simulations of a glass-forming molecular liquid. We show that spatially correlated clusters of low-potential-energy molecules are observable on the time scale of structural relaxation, despite the absence of spatial correlations of potential energy in the instantaneous structure of the system. We find that these structural heterogeneities correlate with dynamical… 
Correlation between dynamical heterogeneities, structure and potential-energy distribution in a 2D amorphous solid
The collective properties of particles in a 2D experimental system which consists of a bi-disperse mixture of colloidal particles confined at an air/water interface are investigated to find a direct correlation between structure and dynamical heterogeneities.
Spatial correlation of the dynamic propensity of a glass-forming liquid.
It is shown that a significant correlation exists between the spatial fluctuations of the dynamic and coordination propensities, and the implications for understanding the length scales of dynamical heterogeneity in glass-forming liquids are discussed.
The interplay between dynamic heterogeneities and structure of bulk liquid water: A molecular dynamics simulation study.
For temperatures higher than that of the dynamic crossover between "fragile" and "strong" liquid behaviors detected around 207 K, the rotational relaxation of supercooled water appears to be remarkably homogeneous, however, the structural parameters do not show homogeneous distributions, and these distributions are different for the two water models.

The quest for a connection between the static and dynamic properties of glass formers at the particle level is in vain, but they demonstrate that such a connection does exist on larger length scales.

It is revealed that medium-range crystalline bond orientational order of the hexagonal close packed structure grows in size and lifetime with increasing packing fraction and dynamic heterogeneity may be a direct consequence of this transient structural ordering, which suggests its origin is thermodynamic rather than kinetic.
Apparent correlations between the static length of relaxation and the linear size of dynamic heterogeneity in fragile liquids
Abstract.The most puzzling aspect of the glass transition observed in laboratory is the decoupling of the dynamics from the structure. As an attempt to reconcile the dynamic and the static
Space and time dynamical heterogeneity in glassy relaxation. The role of democratic clusters.
This work describes the relationship between the d-cluster events and the constraints that the local structure poses on the relaxation dynamics, thus revealing their role in reformulating structural constraints.
Spatiotemporal heterogeneity of local free volumes in highly supercooled liquid.
It is suggested that long-ranged vibration modes facilitate the interactions between fragile regions represented by free volumes, to induce dynamical correlations at a large scale.
Evidence of a two-state picture for supercooled water and its connections with glassy dynamics
This work combines the use of a structural parameter with a minimization technique to yield neat bimodal distributions in a temperature range within the supercooled liquid regime, thus clearly revealing the presence of two populations of differently structured water molecules and elucidate the role of the inter-conversion between the identified two kinds of states.
Calorimetric signature of structural heterogeneity in a ternary silicate glass
We investigate the structural heterogeneity in a silicate glass by hyperquenching–annealing–calorimetry approach. The results show a striking phenomenon: two separated sub-Tg relaxation peaks appear
