Granular fluids and their non-equilibrium phases

Take a glass jar, pour in it some sand and shake it violently: you will get a granular fluid. Very simple to create, very complex to be understood. Indeed the whole theoretical apparatus developed in the 20th century to study

Physical realization of the Glauber quantum oscillator

More than 30 years ago, Glauber theorized the existence of quantum systems to explain the link between the reversible microscopic and irreversible macroscopic scale. The formulation of such model is based on the so-called “rigged Hilbert space” and include irreversibility … Read the rest

Self-Sustained Density Oscillations of Swimming Bacteria Confined in Microchambers

Contagion

Epidemic processes have accumulated over the years a vast amount of research which is coherently reviewed in a comprehensive manner by Claudio Castellano together with Romualdo Pastor-Satorras, Piet Van Mieghem, and Alessandro Vespignani in an article published in Epidemic processes Read the rest

Olfactory Navigation

Pelagic seabirds rely on olfactory maps for oceanic navigation

Seabirds can fly for days across featureless oceans to their preferred feeding locations and then fly back to their nests without getting lost. How they do this has long been a Read the rest

Replica Symmetry Breaking

Experimental evidence of replica symmetry breaking in random lasers

Spin-glass theory is one of the leading paradigms of complex physics and describes condensed matter, neural networks and biological systems, ultracold atoms, random photonics and many other research fields.

Dynamic Coarsening

Crystal surfaces led out of equilibrium by a growth or erosion process may undergo morphological instabilities and develop distinct structures: ondulations, mounds or pyramids, bunches of steps, ripples.

Emergent pattern may increase in size with time by means of a … Read the rest

Silent Flocks

A paper on the collective behaviour of bird flocks, in which a spin wave model is brought to the continuous limit as in fluid elements of a large hydrodynamic system, has been published in Physical Review Letters and it has … Read the rest
