Anomalous segregation dynamics of self-propelled particles [PDF]
New Journal of Physics, 2015 A number of novel experimental and theoretical results have recently been obtained on active soft matter, demonstrating the various interesting universal and anomalous features of this kind of driven systems.

Motional consensus of self-propelled particles [PDF]
Scientific Reports, 2023 The motional consensus of self-propelled particles is studied in both noise-free cases and cases with noise by the standard Vicsek model. In the absence of noise, we propose a simple method, using grid-based technique and defining the normalized variance

Inertial delay of self-propelled particles [PDF]
Nature Communications, 2018 Active matter describes a group of interacting units showing collective motions by constantly consuming energy from the environment, but inertia has largely been overlooked in this context. Scholz et al. show how important it can be by characterizing the

Swarming Transition in Super-Diffusive Self-Propelled Particles [PDF]
Entropy, 2023 A super-diffusive Vicsek model is introduced in this paper that incorporates Levy flights with exponent α. The inclusion of this feature leads to an increase in the fluctuations of the order parameter, ultimately resulting in the disorder phase becoming ...

Hydrodynamic Behavior of Self-Propelled Particles in a Simple Shear Flow [PDF]
Entropy, 2022 The hydrodynamic properties of a squirmer type of self-propelled particle in a simple shear flow are investigated using the immersed boundary-lattice Boltzmann method in the range of swimming Reynolds number 0.05 ≤ Res ≤ 2.0, flow Reynolds number 40 ...

Kinetic Theory of Self-Propelled Particles with Nematic Alignment [PDF]
EntropyWe present the results from kinetic theory for a system of self-propelled particles with alignment interactions of higher-order symmetry, particularly nematic ones. To this end, we use the Landau equation approach, a systematic approximation to the BBGKY

How active forces influence nonequilibrium glass transitions
New Journal of Physics, 2017 Dense assemblies of self-propelled particles undergo a nonequilibrium form of glassy dynamics. Physical intuition suggests that increasing departure from equilibrium due to active forces fluidifies a glassy system.

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.

Inertial self-propelled particles in anisotropic environments
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.
