| Research Abstract |
We have studied theoretically traveling waves and self-propelled soft particles in nonlinear dissipative systems. As a former problem, we investigated the dynamics of Turing patterns under feedback control and derived non-equilibrium phase diagram. In the dynamics of individual self-propelled particles, we have considered not only translational motion but also spinning motion and clarified the properties both in two and three dimensions. It has been revealed that fascinating dynamics emerge due to the couplings among translation, deformation, spinning and external forces. In the dynamics of interacting self-propelled particles, we have shown that traveling bands appear in our system and those bands exhibit soliton-like behavior upon head-on collisions.
