U18.00001: Out-of-equilibrium dynamics of particle systems in infinite dimension Invited Speaker: Elisabeth Agoritsas Dense assemblies of particles are prototypes of structurally disordered systems, such as amorphous solids or yield stress fluids. In infinite dimension their mean-field description becomes exact, and solving their equilibrium dynamics in this limit has been remarkably fruitful in capturing static properties of finite-dimensional systems as well. Here we address their out-of-equilibrium dynamics, paving the way to obtaining a similar infinite-dimensional benchmark for the mechanical or rheological properties of structurally disordered systems. |

U18.00002: Beyond mean-field theories of glassy dynamics Invited Speaker: Giulio Biroli I will present new theoretical frameworks that allow to go beyond the mean-field theory of glassy dynamics. |

U18.00004: Gelation in Soft Matter: from Colloids to Decorated Protein Networks Invited Speaker: Paddy Royall Gelation unites many central issue in soft matter: phase transitions, dynamical arrest and self-assembly. Spinodal Gelation the formation of a network during spinodal decomposition has been recognized in colloids and proteins [1,2]. The competition between dynamical arrest and self-assembly has also been exploited in critical soft matter, where fluctuations associated with a non-equilibrium critical point introduce an additional tunable lengthscale [3]. Here we extend these concepts to a new system of fluorescent proteins, to produce multicomponent networks. We tune the structural properties and functional behavior of these decorated protein networks with a variety of soft matter and biochemical techniques [4]. |

U18.00005: Rigidity and glass transitions in collections of cells and fiber networks Invited Speaker: M. Lisa Manning In biological processes like embryonic development and in cancer metastasis, collective groups of cells must dramatically reorganize and move over substantial distances like a fluid. In other cases, such as the mature lining of the human lung, it is functionally important for the cells to behave as an intact solid, and still other tissues appear to straddle a disordered fluid-solid transition. First, I will discuss a theory for the origin of rigidity and the scaling laws that occur in a broad class of models for biological tissues (including vertex models for confluent cell aggregates and spring network models for extra-cellular matrix), and then I will discuss the anomalous glassy behavior that arises in such models in the presence of thermal or active fluctuations. |
