Pioneering research could be used in future computers
Nobel Committee member explains theory using pastries
Three British physicists working at US universities have won the Nobel Prize in Physics for revealing the secrets of exotic matter.
The 8 million Swedish Krona prize (more than US $931,000) was divided between the three laureates according to their contributions – one half awarded to David Thouless of the University of Washington, and the other half jointly to Duncan Haldane of Princeton University and Michael Kosterlitz of Brown University.
“This year’s laureates opened the door on an unknown world where matter can assume strange states,” said the Nobel Foundation in a statement Tuesday.
“They have used advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids or thin magnetic films”
What was their discovery?
In the early 1970s, Kosterlitz and Thouless overturned the then-current theory that superconductivity could not occur in extremely thin layers.
“They demonstrated that superconductivity could occur at low temperatures and also explained the mechanism – phase transition – that makes superconductivity disappear at higher temperatures,” explained the Foundation.
Around a decade later, Haldane also studied matter that forms threads so thin they can be considered one-dimensional.
A member of the Nobel committee explained the process in a video, using a cinnamon bun, a bagel and a pretzel:
Why is it important?
The physicists’ pioneering research could be used in the next generation of electronics and superconductors – or even quantum computers, as Nobel Committee member Thors Hans Hansson explained.
“People are working very hard in the labs to get new materials which have interesting properties of conducting electricity,” he said.
“And the dream is that this can be used for carrying information.”
Remember when the prize went to…
The Higgs boson, or “God particle,” garnered Francois Englert of Belgium and Peter Higgs of the United Kingdom the Nobel in Physics in 2013.
Five decades ago, Englert and Higgs had the foresight to predict the elusive particle existed – long before scientists at the European Organization for Nuclear Research (CERN) announced they had discovered it in 2012.
The following year, the octogenarian pair shared the Nobel in recognition of their early theoretical brilliance which helped uncover the particle, thought to be a fundamental building block of the universe.

Physics winners are the youngest
With an average age of 55, Nobel physics laureates are the youngest of all laureates.
Australian-born British physicist William Lawrence Bragg was just 25 years old when he won the prize, along with his father William Henry Bragg, for their work on x-ray crystallography in 1915.
Bragg remained the youngest laureate for almost a century, until Malala Yousafzai won the Nobel Peace Prize in 2014.
However, this year the Physics winners are at the upper end of the age bracket – Thouless is 82, Kosterlitz is 74, and Haldane is 65.
Did you know…?
Of the 198 people who have been awarded the Nobel Prize in Physics, just two have been women.
They include Polish-born French physicist Marie Curie, who took the prize in 1903 for her pioneering work in radioactivity. Curie also won the Nobel in Chemistry in 1911.
And German-born American Maria Goeppert-Mayer, who won in 1963 for her discoveries in nuclear shell structure.
