Active Motion of Low-symmetry Particles

Active colloidal systems exhibit intriguing active motion and collective behaviors such as living crystals, and giant fluctuations. The active particles used in experiments so far are of D₂ symmetry, such as spherical or rod-like Janus particles. In contrast, active particles used in theoretical and computational studies often have low symmetries and more diverse shapes. In the talk, we will present our recent research results on designing and fabricating colloidal particles of low symmetries, and our experimental studies of their active motions driven by electrohydrodynamic flows.
