Dynamics and structure in supercooled systems close to the Glass transition ; experiments and simulations. |
|
Résumé |
The glass transition is the dramatic dynamical slowdown one observes when cooling down a liquid or densifying a set of particles into an amorphous state. Here we explore the general features of the particles' dynamics in supercooled systems close to the Glass transition, ranging from simulation of repulsive particles to granular experiments.
We study the relations between the very short term dynamics - essentially made of vibrations - and the long time scale dynamics where strong dynamical heterogeneities appear. We analyse the role and evolution of cooperative displacements and evidence the appearance of non-conserved facilitation when the system approach the glass transition.
The influence of the structure on the dynamics - at a coarse grained level - is also explored by means of numerical studies. |
