Flocking dynamics with voter-like interactions
(IOP Publishing, 2018-03)
We study the collective motion of a large set of self-propelled particles subject to voter-like interactions. Each particle moves on a 2D space at a constant speed in a direction that is randomly assigned initially. Then, ...
Reaction processes among self-propelled particles
(Royal Society of Chemistry, 2018-12-12)
We study a system of self-propelled disks that perform run-and-tumble motion, where particles can adopt more than one internal state. One of those internal states can be transmitted to other particle if the particle carrying ...
Otherwise identical particles with differing, fixed speeds demix under time-reversible dynamics
(American Physical Society, 2020-06-18)
In recent years situations where elsewise identical particles demix when different degrees of freedom do not thermalize have become a research focus in nonequilibrium statistical mechanics. The majority of these models are ...
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 ...
Active colloidal chains with cilia- and flagella-like motion
(IOP Publishing Ltd, 2018-05-04)
It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because the effective diffusiophoretic forces that mediate the interactions of ...
Active colloidal chains with cilia- and flagella-like motion
(Iop publishing LTD, 2018-05)
It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because the effective diffusiophoretic forces that mediate the interactions of ...
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 ...
Phase separation and emergence of collective motion in a one-dimensional system of active particles
(American Institute of Physics, 2019-04-14)
We study numerically a one-dimensional system of self-propelled particles, where the state of the particles is given by their moving direction (left or right), which is encoded by a spin-like variable, and their position. ...
