 abstract = {The central problem in the study of glass-forming liquids and other
glassy systems is the understanding of the complex structural relaxation
and rapid growth of relaxation times seen on approaching the glass
transition. A central conceptual question is whether one can identify
one or more growing length scale(s) associated with this behavior. Given
the diversity of molecular glass-formers and a vast body of
experimental, computational and theoretical work addressing glassy
behavior, a number of ideas and observations pertaining to growing
length scales have been presented over the past few decades, but there
is as yet no consensus view on this question.
In this review, we will summarize the salient results and the state of
our understanding of length scales associated with dynamical slow down.
After a review of slow dynamics and the glass transition, pertinent
theories of the glass transition will be summarized and a survey of
ideas relating to length scales in glassy systems will be presented. A
number of studies have focused on the emergence of preferred packing
arrangements and discussed their role in glassy dynamics. More recently,
a central object of attention has been the study of spatially
correlated, heterogeneous dynamics and the associated length scale,
studied in computer simulations and theoretical analysis such as
inhomogeneous mode coupling theory. A number of static length scales
have been proposed and studied recently, such as the mosaic length scale
discussed in the random first-order transition theory and the related
point-to-set correlation length. We will discuss these, elaborating on
key results, along with a critical appraisal of the state of the art.
Finally we will discuss length scales in driven soft matter, granular
fluids and amorphous solids, and give a brief description of length
scales in aging systems. Possible relations of these length scales with
those in glass-forming liquids will be discussed.},
