Glassy behavior of light
L. Angelani, C. Conti, G. Ruocco +1
We study the nonlinear dynamics of a multi-mode random laser using the methods of statistical physics of disordered systems. A replica-symmetry breaking phase transition is predict…
On the relationship between phase transitions and topological changes in one dimensional models
L. Angelani, G. Ruocco, F. Zamponi
We address the question of the quantitative relationship between thermodynamic phase transitions and topological changes in the potential energy manifold analyzing two classes of o…
Topological properties of the mean field phi^4 model
A. Andronico, L. Angelani, G. Ruocco +1
We study the thermodynamics and the properties of the stationary points (saddles and minima) of the potential energy for a phi^4 mean field model. We compare the critical energy Vc…
Landscapes and Fragilities
G. Ruocco, F. Sciortino, F. Zamponi +2
The concept of fragility provides a possibility to rank different supercooled liquids on the basis of the temperature dependence of dynamic and/or thermodynamic quantities. We reca…
