'Unreasonable Effectiveness of Kinetic Constraints in Glassy Dynamics"

Abstract:
Sometimes the obvious things are the most obscure. One example is the
rigidity of solid bodies which, especially for amorphous materials, we 
do not
yet understand. In this talk I will review the Mode-Coupling Theory of 
glassy
dynamics (with its Random First Order Transition extension), and show that
it is equivalent to an alternative approach based on the notion, crude and
subtle at once, of kinetic constraint. The emerging universality and the
geometrical interpretation of the unusual dynamical scaling laws observed
near the glass transition will be discussed.
