A Density-Independent Model of Self-Propelled Particles
One of the most studied models of collective motion is the Vicsek model [1], which exhibits a continuous phase transition between disordered and ordered motion as an external noise is varied. The particles of the Vicsek model interact with all neighbors within a fixed distance, and the density of the particles is an important parameter of the model. On the other hand, empirical investigations o...
متن کاملActive jamming: self-propelled soft particles at high density.
We study numerically the phases and dynamics of a dense collection of self-propelled particles with soft repulsive interactions in two dimensions. The model is motivated by recent in vitro experiments on confluent monolayers of migratory epithelial and endothelial cells. The phase diagram exhibits a liquid phase with giant number fluctuations at low packing fraction φ and high self-propulsion s...
متن کاملHydrodynamic equations for self-propelled particles: microscopic derivation and stability analysis
Considering a gas of self-propelled particles with binary interactions, we derive the hydrodynamic equations governing the density and velocity fields from the microscopic dynamics, in the framework of the associated Boltzmann equation. Explicit expressions for the transport coefficients are given, as a function of the microscopic parameters of the model. We show that the homogeneous state with...
متن کاملA continuum model for alignment of self-propelled particles with anisotropy and density-dependent parameters
We consider the macroscopic model derived by Degond and Motsch from a time-continuous version of the Vicsek model, describing the interaction orientation in a large number of self-propelled particles. In this article, we study the influence of a slight modification at the individual level, letting the relaxation parameter depend on the local density and taking in account some anisotropy in the ...
متن کاملA continuum model for nematic alignment of self-propelled particles
A continuum model for a population of self-propelled particles interacting through nematic alignment is derived from an individual-based model. The methodology consists of introducing a hydrodynamic scaling of the corresponding mean-field kinetic equation. The resulting perturbation problem is solved thanks to the concept of generalized collision invariants. It yields a hyperbolic but non-conse...
