The following files are included as Electronic Supplementary Information for the paper “Anisotropic Colloidal Transport and Periodic Stick-Slip Motion in Cholesteric Finger Textures” by K. Chen et al.:

S1_alpha90.avi: A video of a Ni disk sedimenting a cholesteric finger texture with 62-μm pitch.  The disk velocity is parallel to gravity, which is perpendicular to the cholesteric axis.  The video was taken at 0.1 frames per second and plays at 3 frames per second (30x real time).

S1_alpha0.avi: A video of a Ni disk sedimenting through a cholesteric finger texture with 60-μm pitch in response to gravity parallel to the cholesteric axis. The disk undergoes stick-slip motion parallel to the axis.  The video was taken at 0.1 frames per second and plays at 5 frames per second (50x real time).

S3_alpha70.avi: A video of a Ni disk sedimenting through a cholesteric finger texture with 60-μm pitch in response to gravity oriented at oblique angle (approximately 70 degrees) to the cholesteric axis.  The disk moves perpendicular to the axis. The video was taken at 0.1 frames per second and plays at 7 frames per second (70x real time).


S4_alpha42: A video of a Ni disk sedimenting through a cholesteric finger texture with 114-μm pitch in response to gravity oriented at an oblique angle (approximately 42 degrees) to the cholesteric axis.  The disk follows a zigzag trajectory.  The video was taken at 0.1 frames per second and plays at 5 frames per second (50x real time).
