Trio win Nobel Physics Prize for exotic matter research
British scientists David Thouless,
Duncan Haldane and Michael Kosterlitz won the Nobel Physics Prize on
Tuesday for revealing the secrets of exotic matter, the Nobel jury said.
“This year’s laureates opened the door
on an unknown world where matter can assume strange states. They have
used advanced mathematical methods to study unusual phases, or states,
of matter, such as superconductors, superfluids or thin magnetic films.
Thanks to their pioneering work, the hunt is now on for new and exotic
phases of matter,” it said.
The laureates will share the eight
million Swedish kronor (around $931,000 or 834,000 euros) prize sum.
Thouless won one-half of the prize, while Haldane and Hosterlitz share
the other half.
The jury said their pioneering work “has
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.”
Topology, in which the three laureates
specialise, is a branch of mathematics that investigates physical
properties of matter and space that remain unchanged under deforming
forces, including stretching.
It holds exceptional promise for quantum
computing and tiny quantum devices as topological states can transport
energy and information without overheating, unlike traditional quantum
mechanics.
“They demonstrated that
superconductivity could occur at low temperatures and also explained the
mechanism, phase transition, that makes superconductivity disappear at
higher temperatures,” the jury noted.
In the 1980s, Thouless was able to
explain a previous experiment with very thin electrically conducting
layers in which conductance was precisely measured as integer steps.
“He showed that these integers were
topological in their nature. At around the same time, Duncan Haldane
discovered how topological concepts can be used to understand the
properties of chains of small magnets found in some materials.”
