Researchers at the University of Strathclyde have revealed a new technique for moulding materials into complicated patterns by using "twisted" light.The findings of the research were published in the journal 'Physical Review Letters'.When atoms are cooled to temperatures close to absolute zero (-273 degrees C), they stop behaving like particles and start to behave like waves.Atoms in this condition, which are known as Bose-Einstein condensates (BECs), are useful for purposes such as the realisation of atom lasers, slow light, and quantum simulations for understanding the complex behaviour of materials like superconductors and superfluids, and the precision measurement technique of atom interferometry.The Strathclyde study has shown that when twisted light is shone onto a moving BEC, it breaks into clusters of BEC droplets that move following the light's features, with the number of droplets equal to twice the number of light twists. Altering the properties of the light beam can change both the number of BEC droplets and the way that they move.Grant Henderson, a PhD student in Strathclyde's Department of Physics, is the lead author of the paper. He said: "By shining a laser beam onto a BEC, we can influence how it behaves. When the laser beam is 'twisted,' it has a helical phase profile and carries orbital angular momentum (OAM). Laser beams with OAM can trap and rotate microscopic particles, behaving like an optical spanner."This method of shining twisted light through ultracold atoms opens a new and simple way of sculpting matter into unconventional and complex shapes. It has the potential for the design of novel quantum devices such as atomtronic circuits and ultra-sensitive detectors."( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
