David J. Thouless

David James Thouless (; 21 September 1934 – 6 April 2019) was a British condensed-matter physicist. He was awarded the 1990 Wolf Prize and a laureate of the 2016 Nobel Prize for physics along with F. Duncan M. Haldane and J. Michael Kosterlitz for theoretical discoveries of topological phase transitions and topological phases of matter.

Education

Born on 21 September 1934 in Bearsden, Scotland to English parents, Priscilla (Gorton) Thouless, an English teacher, and Robert Thouless a psychologist and broadcaster. David Thouless was educated at St Faith's School then Winchester College and earned a Bachelor of Arts degree in Natural Sciences from the University of Cambridge as an undergraduate student of Trinity Hall, Cambridge. He obtained his PhD at Cornell University, where Hans Bethe was his doctoral advisor.

Career and research

Thouless was a postdoctoral researcher at Lawrence Berkeley Laboratory, University of California, Berkeley, and also worked in the physics department from 1958 to 1959, giving a course on atomic physics. He was the first director of studies in physics at Churchill College, Cambridge, in 1961–1965, professor of mathematical physics at the University of Birmingham in the United Kingdom in 1965–1978, and professor of applied science at Yale University from 1979 to 1980, before becoming a professor of physics at the University of Washington in Seattle in 1980. Thouless made many theoretical contributions to the understanding of extended systems of atoms and electrons, and of nucleons. He also worked on superconductivity phenomena, properties of nuclear matter, and excited collective motions within nuclei.

Thouless made many important contributions to the theory of many-body problems. For atomic nuclei, he cleared up the concept of 'rearrangement energy' and derived an expression for the moment of inertia of deformed nuclei. In statistical mechanics, he contributed many ideas to the understanding of ordering, including the concept of ' topological ordering'. Other important results relate to localised electron states in disordered lattices.

Personal life

Thouless married Margaret Elizabeth Scrase in 1958 and together they had three children. In 2016, Thouless was reported to be suffering from dementia. He died on 6 April 2019 in Cambridge, aged 84.
