Individual and collective dynamics of self-propelled soft particles
Deformable self-propelled particles provide us with one of the most important
nonlinear dissipative systems, which are related, for example, to the motion of
microorganisms. It is emphasized that this is a subject of localized objects in
non-equilibrium open systems. We introduce a coupled set of ordinary
differential equations to study various dynamics of individual soft particles
due to the nonlinear couplings between migration, spinning and deformation. By
introducing interactions among the particles, the collective dynamics and its
collapse are also investigated by changing the particle density and the
interaction strength. We stress that assemblies of self-propelled particles
also exhibit a variety of non-equilibrium localized patterns
