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
Talk: Martin Weitz – November 2 2017
Aula Conversi, Dipartimento di Fisica (I piano edificio Marconi)
3pm-4pm (info)
Martin Weitz (Universität Bonn)
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

Complexity models in biophysics and material science
Abstract
I will review three topics of my recent activity:
- Fractional Langevin Equation and its application to linear stochastic models.
The Generalized Elastic Model accounts for the dynamics of several physical systems, such as polymers, fluctuating interfaces, growing surfaces, membranes, proteins and file systems.

Nanofotonica nonlineare su metalli e grafene: sfide e opportunità
Abstract:
La nanofotonica è la scienza che studia il confinamento della luce in regioni di spazio con dimensioni inferiori alla lunghezza d’onda. In mezzi dielettrici convenzionali questo non è possibile a causa della diffrazione, che pone il limite fisico della lunghezza d’onda come minima distanza di confinamento della luce.… Read the rest

Gaussian, non Gaussian and Anomalous diffusion to improve medical diagnosis
In the biomedical field, Diffusion Magnetic Resonance (DMR) images provide a measure of water proton displacements by probing motion on the mesoscopic length scale (around 10-20 µm), which is orders of magnitude smaller than the macroscopic MR resolution (typically 1-2 millimetres for clinical MR scanners).
Therefore, independently of image resolution (which is linked to the hardware of the NMR scanner) we can obtain microstructural information of human tissue at the mesoscopic length scale.… Read the rest
Nonequilibrium statistical physics: A modern perspective (book)
Paolo Politi and Roberto Livi have published a book:
Nonequilibrium statistical physics: A modern perspective.
Statistical mechanics has been proven to be successful at describing physical systems at thermodynamic equilibrium. Since most natural phenomena occur in nonequilibrium conditions, the present challenge is to find suitable physical approaches for such conditions: this book provides a pedagogical pathway that explores various perspectives.… Read the rest
