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.

According to this theory, identical systems under identical conditions may reach different states. This effect is known as replica symmetry breaking and is revealed by the shape of the probability distribution function of an order parameter named the Parisi overlap.… Read the rest

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 coarsening process which may continue forever or stop at some relevant length scale.

Paolo Politi’s group has studied the dynamics for three different types of instabilities, stressing the main physical ingredients: kinetic, energetic and athermal instabilities.… 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 been the subject of a synopsis in the APS magazine Physics.

Both spin and density waves can propagate throughout flocks, but in some cases their contributions are quickly damped.… Read the rest
