Séminaire Café (Interne)
Il s’agit d’un exposé assez court (20 min) et assez informel.
Prière aux conférencier·ère·s de ne jamais dépasser 30 min et de vérifier la compatibilité avec le projecteur avant le séminaire.
Les séminaires ont lieu les jeudis après la réunion du laboratoire qui débute à 13h30 dans la bibliothèque du labo sur le campus Jussieu, Barre Cassan, Bât A, 1er étage.

| 16 mai | Haim Diamant Tel Aviv University What hydrodynamic interactions tell us about the colloidal glass transition The motions of colloidal particles slow down tremendously as the suspension approaches the glass transition. This makes an accurate study of the transition a decades-long challenge. We use an indirect approach to bypass this difficulty. Instead of examining the dynamics of the glass-forming particles directly, we learn about it from the dynamics of small tracers that freely move in the host liquid. Correlations between the thermal motions of the tracers report on the flow response of the host liquid, which in turn reports on the state of the larger particles obstructing the flow. A model-independent phenomenological theory predicts distinctive signatures of the glass transition in these hydrodynamic correlations : (a) the power of their decay with relative distance changes ; (b) a length scale related to this decay steeply increases with the increasing viscosity ; and (c) certain correlations switch sign. These predictions are confirmed by experiment. |
