Activities

I am researcher at ISC since the beginning of 2009 . My activity mainly concerns granular systems and non-equilibrium statistical mechanics, from Fluctuation-Dissipation theories to non-equilibrium stochastic processes. In recent years I, with my co-worker have obtained many new experimental and theoretical results.

 

  • For our main experimental results, please have a look to my home page.
  • For recent theoretical results in non-equilibrium statistical mechanics, here you can have a brief survey:

 

- studied in depth the generalization of FDT to non-equilibrium (stationary) systems, see this paper for a review.

- edited a book of contributions about Large Deviations theory in physics, see this book

- wrote a book on granular fluids, see this book

- generalized the Einstein relation (and other equilibrium FDT relations) to out-of-equilibrium fludiized granular systems, see this paper

- obtained a closed description of an intruder in a granular fluid, with memory and different temperatures, obtaining a verification of the Fluctuation theorem for the fluctuating entropy production due to the heat exchange between the intruder and the surrounding (coupled) fluid, see this paper.

- shown the existence of a ratchet-like phenomenon for asymmetric intruders in a granular fluid, see this paper;

- shown the existence of a non-equibrium correlation length in driven granular fluids, see this paper

- introduced a new model of driven Lorentz gas, see this paper

- shown the importance of correlations among degrees of freedom and the (consequent) effect of coarse-graining in entropy production, see this paper and this paper

- shown the existence of an "H-theorem" for driven granular fluids, see this paper

- introduced a model for a small/finite time heat engine, see this paper

- introduced a lattice model for the evolution of the velocity field in a granular fluid, where a rigorous derivation of the hydrodynamic limit is possible, see this paper

 

  • An other important and parallel activity includes the study of agents-based models for the dynamics of linguistic evolution, see for instance this paper and this other one.
