Dynamics of deformable self-propelled particles

Abstract:
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 of the center of gravity, a second rank tensor and a third rank tensor to represent the deformation is derived starting with an excitable reaction diffusion system. A rich variety of dynamics has been obtained by numerical simulations of a single particle such as circular motion, zig-zag motion and chaotic motion depending the parameters.
