The transport properties of glass-forming systems have many features that are not found in normal liquids. Among them is a very strong sensitivity of the relaxation times upon a change in temperature and the presence of so-called dynamical heterogeneities. In this review we discuss these unusual properties and present the results of a simple lattice gas model that helps to understand the origin...

We consider markets with heterogeneously ambiguous assets and ambiguity-averse investors whose preferences are a parsimonious extension of the mean–variance framework. study portfolio choice trade upon arrival public information, show systematic departures from predictions standard theory, that occur in direction empirical regularities. In particular, our theory speaks to several phenomena unif...

Kinetically constrained models (KCM) are systems with trivial thermodynamics but often complex dynamical behavior due to constraints on the accessible paths followed by the system. Exploring these properties, the KobAndersen (KA) model was introduced to study the slow dynamics of glass forming liquids and later extended to granular materials. In this last context, we present new results on the ...
