COBBS – Computer Vision and Tracking

The raw data gathered from the experimental work consists of three sequences of images, one from each camera, for each flocking/swarming event. Each sequence may consist of up to 2700 images, meaning a single event could have a total of … Read the rest

COBBS – Non-biting Midge Experiment

Our search for midge swarms has taken us to many of the public parks within Rome including Riserva Naturale Valle dell’Aniene, Villa Paganini, Villa Torlonia, Parco dell’Acquedotto, Villa Ada, Laghetto dell’EUR and Ponte Tazio. Basically any place with an aquatic … Read the rest

COBBS – Collective Behaviour in Biological Systems

From bird flocks to fish schools, from insect swarms to cell colonies, collective behaviour is a very widespread phenomenon in many biological systems. It is hard to define, but easy to recognize. What are the mechanisms regulating collective behaviour in Read the rest

COBBS – Laboratory

The COBBS Laboratory is housed on the 4th floor of the Fermi Building, Sapienza University. This is our main lab space and houses the experimental team. The numerical analysis and computer vision teams are located two doors down the hallway … Read the rest

Metastable states and supersymmetry

Both the static and the dynamical behaviour occurring in mean field spin glass models models can be interpreted as consequences of the complex (free) energy landscape that spin glasses have, with many minima, valleys and saddles. Traditionally, much attention has … Read the rest

Field theory for finite dimensional spin glasses

Many features predicted by mean field spin glass models, such as the behaviour of susceptibilities and correlation functions or the occurrence of aging and off-equilibrium dynamics, are qualitatively observed in experiments, suggesting that the mean field scenario may hold for … Read the rest

Spin Glasses: a brief introduction

Spin Glasses are dilute magnetic alloys where the interactions between spins are randomly ferromagnetic or anti-ferromagnetic, and are considered as paradigmatic examples of frozen disorder. The presence of disorder (the random interactions) induces frustration and a greater difficulty for the … Read the rest

What is Econophysics?

Collective phenomena in economics, social sciences and ecology are very attractive for statistical physicists, especially in view of the empirical abundance of non-trivial fluctuation patterns and statistical regularities — think of returns in financial markets or of allometric scaling in … Read the rest

STARFLAG: a project on collective animal behaviour

Collective animal behaviour is a fascinating phenomenon. How does global co-ordination emerge in a flock of thousands starlings swirling at dusk? How does a school of sardines organize in a circular pattern? What is the evolutionary function of collective behaviour? Read the rest
