DESCRIPTION:Prof. Matthieu Wyart\nThe glass transition is a long-standing 
 problem of condensed matter. When a liquid is cooled down sufficiently rap
 idly to avoid crystallization\, its dynamics slows down very rapidly until
  a glass is formed\, whose properties differ qualitatively from crystallin
  materials. The origin for both the sudden dynamical slowing down and the 
 anomalous properties of the glassy solid phase are debated. These question
 s are related to how a physical system can explore a complex\, rugged free
  energy landscape with many meta-stable states.  Arguably the most popula
 r theory for these phenomena is that the glass transition is controlled by
  a thermodynamic transition leading to a growing “hidden" order whose ch
 aracteristic length scale diverges at some finite temperature. Here we arg
 ue\, based on the recent finding that certain Monte-Carlo algorithms can e
 ssentially get rid of the dynamical slowing downnear the glass transition\
 , that these theories do not apply\, and discuss alternative views-.
