Rodeo in liquid crystal: Unprecedented level of control over defects

31 marzo 2015

Scientists have achieved an unprecedented level of control over defects in liquid crystals that can be engineered for applications in liquid matter photonics. Sitting with a joystick in the comfort of their chairs, scientists can play «rodeo» on a screen magnifying what is happening under their microscope. They rely on optical tweezers to manipulate an intangible ring created out of liquid crystal defects capable of attaching a microsphere to a long thin fiber.
