The study of "strange states" of matter, which may one day yield superfast and small computers, earned British scientists David Thouless, Duncan Haldane and Michael Kosterlitz the Nobel Physics Prize today.
The study of "strange states" of matter, which may one day yield superfast and small computers, earned British scientists David Thouless, Duncan Haldane and Michael Kosterlitz the Nobel Physics Prize today.
The trio, all based in the US working in the highly- specialised mathematics field of "topology", studied unusual phases or states of matter. "This year's laureates opened the door on an unknown world where matter can assume strange states," the Nobel jury said. "Thanks to their pioneering work, the hunt is now on for new and exotic phases of matter."
The jury said there were hopes that their discoveries would have future uses in the fields of materials science and electronics, especially at the super-small quantum scale. For now, the scientists' discoveries remain in the realm of research. Thouless won half of the eight million Swedish kronor (around US $931,000) prize, while Haldane and Kosterlitz share the other half.
Topology is a branch of mathematics that investigates the physical properties of matter and space - shape in essence - that remain unchanged under certain deforming forces. These include stretching, compressing and bending, but not piercing, tearing or gluing. An often-used example is a rubber coffee cup being bent, twisted and reshaped into a donut -- for topologists the two shapes are indistinguishable, though to the rest of us they are completely different. In practical terms, these properties of matter may one day lead to the reshaping of common materials into "topological states" that can transport energy and information in very small spaces without overheating.

The trio's pioneering work "boosted frontline research in condensed matter physics, not least because of the hope that topological materials could be used in new generations of electronics and superconductors, or in future quantum computers," said the Nobel jury. In the early 1970s, Kosterlitz and Thouless overturned the theory that superconductivity or suprafluidity could not occur in very thin layers of material. Superconductivity is when electricity flows through a material without experiencing any resistance or losing energy as heat, while suprafluidity is when a fluid flows without any friction.
For his part, Haldane discovered how topological concepts applied to chains of small magnets in certain materials. Haldane said his prizewinning discovery had been serendipitous. "Most of the big discoveries are done that way: you stumble on it and you have the luck to recognise you have something very interesting," he told reporters at the Nobel press conference via videolink.
