Inertial self-propelled particles in anisotropic environments [PDF]
Communications Physics, 2023 Self-propelled particles in anisotropic environments can exhibit a motility that depends on their orientation. This dependence is relevant for a plethora of living organisms but difficult to study in controlled environments.

Motility-sorting of self-propelled particles in microchannels [PDF]
EPL (Europhysics Letters), 2014 Spontaneous segregation of run-and-tumble particles with different velocities in microchannels is investigated by numerical simulations. Self-propelled particles are known to accumulate in the proximity of walls. Here we show how fast particles expel slower ones from the wall leading to a segregated state.

Pattern phase transitions of self-propelled particles: gases, crystals, liquids, and mills [PDF]
New Journal of Physics, 2016 To understand the collective behaviors of biological swarms, flocks, and colonies, we investigated the non-equilibrium dynamic patterns of self-propelled particle systems using statistical mechanics methods and H -stability analysis of Hamiltonian ...

Mathematical models of self-propelled particles
Mathematical Models and Methods in Applied Sciences, 2017 This paper presents the papers published in two special issues devoted to the modeling of large systems of self-propelled particles. The contents of these papers are presented in the general framework of the conceptual analytic difficulties and of the computational problems that are met when dealing with this class of systems.

Chemotaxis of Cargo-Carrying Self-Propelled Particles [PDF]
Physical Review Letters, 2021 Active particles with their characteristic feature of self-propulsion are regarded as the simplest models for motility in living systems. The accumulation of active particles in low activity regions has led to the general belief that chemotaxis requires additional features and at least a minimal ability to process information and to control motion.

Deformable Self-Propelled Particles [PDF]
Physical Review Letters, 2009 A theory of self-propelled particles is developed in two dimensions assuming that the particles can be deformed from a circular shape when the propagating velocity is increased. A coupled set of equations in terms of the velocity and a tensor variable to represent the deformation is introduced to show that there is a bifurcation from a straight motion ...

Research Paper: Self-propelled Magnetic Particles in the Presence of an External Homogenous Magnetic Field [PDF]
فیزیک کاربردی ایران, 2021 In this paper, the behavior of the magnetic swimmers has been simulated in the presence of an external magnetic field. The studied system is formed of spherical self-propelled particles that have magnetic properties and are suspended in a box.

Collective pattern formations of animals in active matter physics
Biophysics and Physicobiology, 2021 Active matter refers to systems composed of elements that are self-propelled by the dissipation of energy, in which dynamical patterns emerge, as is the case of flocks of birds and schools of fish.
