Inertial self-propelled particles [PDF]
The Journal of Chemical Physics, 2021 We study how inertia affects the behavior of self-propelled particles moving through a viscous solvent by employing the underdamped version of the active Ornstein–Uhlenbeck model. We consider both potential-free and harmonically confined underdamped active particles and investigate how the single-particle trajectories change as the drag coefficient is ...

Collective dynamics of dipolar self-propelled particles
Physical Review E, 2023 We present a numerical study of the collective behavior of self-propelled particles for which dipolar interactions are considered. These are obtained by introducing pointlike magnetic dipoles in the particles. Various dynamical regimes are found depending on three major parameters: the density of particles, the ratio Γ defined as the competition ...

Soft deformable self-propelled particles [PDF]
EPL (Europhysics Letters), 2012 In this work we investigate the collective behavior of self-propelled particles that deform due to local pairwise interactions. We demonstrate that this deformation alone can induce alignment of the velocity vectors. The onset of collective motion is analyzed.

Self-Propelled Janus Particles
, 2021 Design and operation of Janus particles have a great potential for applications in fields such as environmental remediation, electronic engineering, bio-imaging, bio-sensing, drug delivery and other biomedical tasks. Current research aims to imitate the molecular motors of biological systems by creating micro- and nano-scale particles which can exploit

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.

Random walks of intermittently self-propelled particles
Physical Review ResearchMotivated by various recent experimental findings, we propose a dynamical model of intermittently self-propelled particles: active particles that recurrently switch between two modes of motion, namely an active run state and a turn state, in which self ...

Pattern phase transitions of self-propelled particles: gases, crystals, liquids, and mills
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 ...

Unsupervised learning of collective patterns in self-propelled particles through persistent homology [PDF]
EPJ Web of ConferencesWe propose an approach for systematically clustering and visualizing the diverse patterns generated from a system of self-propelled particles. To extract the topological features of these patterns, we integrate topological data analysis based on ...
