Self-propelled particles with fluctuating speed and direction of motion in two dimensions
(American Physical Society, 2007-12)
We study general aspects of active motion with fluctuations in the speed and the direction of motion in two dimensions. We consider the case in which fluctuations in the speed are not correlated to fluctuations in the ...
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 ...
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, ...
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 ...
Theoretical analysis of metallic-nanodimer thermoplasmonics for phototactic nanoswimmers
(American Chemical Society, 2020-02)
We assess the potentiality of several geometries of metallic nanodimers (one of the simplest thermoplasmonic systems) as candidates for active particles (nanoswimmers) propelled and controlled by light (phototaxis). The ...
