Complex network structure of flocks in the Vicsek Model with Vectorial Noise
(World Scientific, 2013-09)
In the Vicsek Model (VM), self-driven individuals try to adopt the direction of movement of their neighbors under the in°uence of noise, thus leading to a noise-driven order–disorder phase transition. By implementing the ...
Complex Network Structure of Flocks in the Standard Vicsek Model
(Springer, 2013-09)
In flocking models, the collective motion of self-driven individuals leads to the formation of complex spatiotemporal patterns. The Standard Vicsek Model (SVM) considers individuals that tend to adopt the direction of ...
Temporal correlations in the Vicsek model with vectorial noise
(Elsevier Science, 2018-07-27)
We study the temporal correlations in the evolution of the order parameter ϕt for the Vicsek model with vectorial noise by estimating its Hurst exponent H with detrended fluctuation analysis (DFA). We present results on ...
Gregarious versus individualistic behavior in Vicsek swarms and the onset of first-order phase transitions
(Elsevier Science, 2013-04)
The standard Vicsek model (SVM) is a minimal non-equilibrium model of self-propelled particles that appears to capture the essential ingredients of critical flocking phenomena. In the SVM, particles tend to align with each ...
Self-propelled Vicsek particles at low speed and low density
(American Physical Society, 2019-05-02)
We study through numerical simulation the Vicsek model for very low speeds and densities. We consider scalar noise in two and three dimensions and vector noise in three dimensions. We focus on the behavior of the critical ...
Equilibrium and dynamical behavior in the Vicsek model for self-propelled particles under shear
(Versita, 2012-06)
The effects of an externally imposed linear shear profile in the Vicsek model of self-propelled particles is investigated via computer simulations. We find that the applied field changes in a relevant way both the equilibrium ...
