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
Accés obertWe 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 ... -
Effect of risk perception on epidemic spreading in temporal networks
Moinet, Antoine; Pastor Satorras, Romualdo; Barrat, Alain (American Chemical Society (ACS), 2018-01-31)
Article
Accés obertMany progresses in the understanding of epidemic spreading models have been obtained thanks to numerous modeling efforts and analytical and numerical studies, considering host populations with very different structures and ... -
Generalized voterlike model on activity-driven networks with attractiveness
Moinet, Antoine; Barrat, Alain; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2018-08-06)
Article
Accés obertWe study the behavior of a generalized consensus dynamics on a temporal network of interactions, the activity-driven network with attractiveness. In this temporal network model, agents are endowed with an intrinsic activity ... -
Glass transition and random walks on complex energy landscapes
Baronchelli, Andrea; Barrat, Alain; Pastor Satorras, Romualdo (2009-08)
Article
Accés obertWe present a simple mathematical model of glassy dynamics seen as a random walk in a directed weighted network of minima taken as a representation of the energy landscape. Our approach gives a broader perspective to previous ... -
Immunization strategies for epidemic processes in time-varying contact networks
Starnini, Michele; Machens, Anna; Cattuto, Ciro; Barrat, Alain; Pastor Satorras, Romualdo (2013)
Article
Accés obertpreading processes represent a very efficient tool to investigate the structural properties of networks and the relative importance of their constituents, and have been widely used to this aim in static networks. Here we ... -
Random walks on temporal networks
Starnini, Michele; Baronchelli, Andrea; Barrat, Alain; Pastor Satorras, Romualdo (2012)
Article
Accés obertMany natural and artificial networks evolve in time. Nodes and connections appear and disappear at various time scales, and their dynamics has profound consequences for any processes in which they are involved. The first ... -
Rate equation approach for correlations in growing network models
Barrat, Alain; Pastor Satorras, Romualdo (2005-03-22)
Article
Accés obertWe propose a rate equation approach to compute two vertex correlations in scale-free growing network models based on the preferential attachment mechanism. The formalism, based on previous work of Szabó et al. [Phys. Rev. ...
