The aversion of hydrophobic solutes for water drives diverse interactions and assemblies across materials science, biology beyond. % Here, we review the theoretical, computational experimental developments which underpin a contemporary understanding effects. We discuss how an density fluctuations in bulk can shed light on fundamental differences hydration molecular macroscopic solutes; these di...

Within a dynamical description of nuclear fragmentation, based on the liquid-gas phase transition scenario, we explore the relation between neutron-proton density fluctuations and nuclear symmetry energy. We show that, along the fragmentation path, isovector fluctuations follow the evolution of the local density and approach an equilibrium value connected to the local symmetry energy. Higher-de...
