    • Effects of heterogeneous social interactions on flocking dynamics 

      Miguel Lopez, M. Del Carmen; Parley, Jack Thomas; Pastor Satorras, Romualdo (2018-02-08)
      Article
      Open Access
      Social relationships characterize the interactions that occur within social species and may have an important impact on collective animal motion. Here, we consider a variation of the standard Vicsek model for collective ...
    • Growth of oriented chains in dipolar colloids 

      Miguel Lopez, M. Del Carmen; Pastor Satorras, Romualdo (1999-11-29)
      Article
      Restricted access - publisher's policy
      We investigate the dynamics of the irreversible aggregation of linear rigid chains oriented along a preferred direction. We propose a Monte Carlo model, whose key ingredient is a logarithmically corrected anisotropic ...
    • Kinetic growth of field-oriented chains in dipolar colloidal solutions 

      Miguel Lopez, M. Del Carmen; Pastor Satorras, Romualdo (1999-01)
      Article
      Open Access
      Experimental studies on the irreversible growth of field-induced chains of dipolar particles suggest an asymptotic power-law behavior of several relevant quantities. We introduce a Monte Carlo model of chain growth that ...
    • Scalar model of flocking dynamics on complex social networks 

      Miguel Lopez, M. Del Carmen; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2019-10-14)
      Article
      Open Access
      We investigate the effects of long-range social interactions in flocking dynamics by studying the dynamics of a scalar model of collective motion embedded in a complex network representing a pattern of social interactions, ...
    • Velocity fluctuations and hydrodynamic diffusion in sedimentation 

      Miguel Lopez, M. Del Carmen; Pastor Satorras, Romualdo (2001-01-23)
      Article
      Open Access
      We study non-equilibrium velocity fluctuations in a model for the sedimentation of non-Brownian particles experiencing long-range hydrodynamic interactions. The complex behavior of these fluctuations, the outcome of the ...
