Self-propelled Worm-like Filaments: Spontaneous Spiral Formation, Structure, and Dynamics

, 2015
Worm-like filaments that are propelled homogeneously along their tangent vector are studied by Brownian dynamics simulations. Systems in two dimensions are investigated, corresponding to filaments adsorbed to interfaces or surfaces.
