Two University of Otago physics students have pushed the frontiers of quantum technology by helping develop laser-operated "optical tweezers" that precisely split clouds of ultracold atoms and smash them together.
Kris Roberts and Thomas McKellar have added significantly to cutting-edge research on ultracold atoms, which interact at temperatures of less than a millionth of a degree above absolute zero.
Absolute zero is about minus 273.15dsC.
Danish-born Otago lead researcher and physicist Dr Niels Kjaergaard said there were many potential applications from the new research. These included developing tools for probing microscopic structures and sensors that could map minute variations in magnetic fields.
In 1998, Otago physicists became the first scientists in the southern hemisphere to create a novel state of matter - known as Bose-Einstein Condensate - in which thousands of atoms enter a quantum state and often behave as if they were a single atom.
