Event details

Many glassy systems display a competition between active and inactive histories. I will present a way of describing quantitatively this 'phase coexistence' in the space of trajectories. For kinetically constrained systems, analytic computations can be done at the mean-field level. We obtain that the dynamics takes place at a first-order coexistence line between active and inactive dynamical phases. Numerical simulations confirm the mean-field phenomonology in finite dimensions.
