Extended Data Fig. 6: Dipole reorientation induced by air bubble sliding.
From: Multistable polar textures in geometrically frustrated nematic liquid crystals
Schematic and polarized light micrographs showing the creation of striped domains by a sliding air bubble underwater on an LC surface with uniformly aligned dipoles. Bubble sliding in the direction of the dipole alignment leads to net zero total rotation from left to right while sliding against the dipolar alignment causes a full 360o rotation (a double Néel wall). Single-headed arrows indicate the orientation of elastic dipoles, with the arrow color representing the orientation as defined by Extended Data Fig. 2a. Crossed, double-headed arrows indicate the direction of the crossed polarizers.
