Glassy slowdown and amorphous order
Abstract:- Upon approaching the glass transition a liquid gets extremely sluggish
without obvious structural changes. Despite decades of work, the physical
origin of this glassy slowdown remains controversial. A common explanation
relies on the increasing roughness of the underlying free-energy landscape,
but the theoretical and experimental underpinnings of this scenario are
still lacking. In this talk, I will survey recent advances that let us
unambiguously identify and track the growing amorphous order, a
manifestation of the rarefaction of metastable states in the rugged
landscape. I will further explore the crucial role this order plays in
driving the glassy slowdown. [video]
