Ionic liquids (ILs) are a special category of molten salts solely composed of ions with varied
molecular symmetry and charge delocalization. The versatility in combining varied cation …

The physics of the glass transition and amorphous materials continues to attract the attention
of a wide research community after decades of effort. Supercooled liquids and glasses have …

All soluble proteins populate conformational ensembles that together constitute the native
state. Their fluctuations in water are intrinsic thermodynamic phenomena, and the …

A theoretical perspective is provided on the glass transition in molecular liquids at thermal
equilibrium, on the spatially heterogeneous and aging dynamics of disordered materials …

Amorphous solids, or glasses, are distinguished from crystalline solids by their lack of long-
range structural order. At the level of two-body structural correlations, glassformers show no …

A great success of solid state physics comes from the characterization of crystal structures in
the reciprocal (wave vector) space. The power of structural characterization in Fourier space …

As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

The low-temperature dynamics of ultraviscous liquids hold the key to understanding the
nature of glass transition and relaxation phenomena, including the potential existence of an …

Understanding the physics of glass formation remains one of the major unsolved challenges
of condensed matter science. As a material solidifies into a glass, it exhibits a spectacular …

We provide here a brief perspective on the glass transition field. It is an assessment, written
from the point of view of theory, of where the field is and where it seems to be heading. We …
