PRX: Relating Topological Determinants of Complex Networks to Their Spectral Properties: Structural and Dynamical Effects
Claudio Castellano has published Relating Topological Determinants of Complex Networks to Their Spectral Properties: Structural and Dynamical Effects in Physical Review X.
In many social and biological systems, the pattern of interactions is described by complex networks—mathematical constructions composed of points (vertices) representing individuals, joined by lines (edges), standing for pairwise interactions between them. These structures are important because they affect the behavior of the dynamical processes they mediate.… Read the rest

Bose-Einstein condensation has been observed with cold atomic gases,
exciton-polaritons, and more recently with photons in a dye-filled optical
microcavity. I will here describe recent measurements of our Bonn group
determining the heat capacity of a two-dimensional photon gas in the regime
around the Bose-Einstein phase transition.… Read the rest
