    • Complex networks and glassy dynamics: walks in the energy landscape 

      Moretti, Paolo; Baronchelli, Andrea; Barrat, Alain; Pastor Satorras, Romualdo (Institute of Physics (IOP), 2010-03)
      Article
      Open Access
      We present a simple mathematical framework for the description of the dynamics of glassy systems in terms of a random walk in a complex energy landscape pictured as a network of minima. We show how to use the tools developed ...
    • Generalized voter-like models on heterogeneous networks 

      Moretti, Paolo; Baronchelli, Andrea; Starnini, Michele; Pastor Satorras, Romualdo (Springer, 2013)
      Part of book or chapter of book
      Restricted access - publisher's policy
      This Chapter presents a generalized model of consensus formation, which is able to encompass all previous formulations of copy/invasion processes inspired by variations on the voter model and the Moran process. It considered ...
    • Heterogenous mean-field analysis of a generalized voter-like model on networks 

      Moretti, Paolo; Liu, S.Y.; Baronchelli, Andrea; Pastor Satorras, Romualdo (Springer, 2012-03)
      Article
      Open Access
      We propose a generalized framework for the study of voter models in complex networks at the heterogeneous mean-field (HMF) level that (i) yields a unified picture for existing copy/invasion processes and (ii) allows for ...
    • Mean-field analysis of the q-voter model on networks 

      Moretti, Paolo; Liu, Suyu; Castellano, Claudio; Pastor Satorras, Romualdo (2013-04-01)
      Article
      Open Access
      We present a detailed investigation of the behavior of the nonlinear q-voter model for opinion dynamics. At the mean-field level we derive analytically, for any value of the number q of agents involved in the elementary ...
    • Yielding and irreversible deformation below the microscale: surface effects and non-mean-field plastic avalanches 

      Moretti, Paolo; Cerruti, Benedetta; Miguel, M. Carmen (2011-06-07)
      Article
      Open Access
      Nanoindentation techniques recently developed to measure the mechanical response of crystals under external loading conditions reveal new phenomena upon decreasing sample size below the microscale. At small length scales, ...
