Education

Born on 21 September 1934 in Bearsden, Scotland [10] to English parents, Priscilla (Gorton) Thouless, an English teacher, and psychologist and broadcaster, Robert Thouless, [11] David Thouless was educated at 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. [1] He obtained his PhD at Cornell University, [5] [12] where Hans Bethe was his doctoral advisor. [4] [13]

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. [7] [14] [15] 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, [16] and professor of applied science at Yale University from 1979 to 1980, [15] before becoming a professor of physics at the University of Washington [17] in Seattle in 1980. [16] Thouless made many theoretical contributions to the understanding of extended systems of atoms and electrons, and of nucleons. [18] [19] [7] He also worked on superconductivity phenomena, properties of nuclear matter, and excited collective motions within nuclei. [18] [19] [7]

Thouless made many important contributions to the theory of many-body problems. [7] For atomic nuclei, he cleared up the concept of 'rearrangement energy' and derived an expression for the moment of inertia of deformed nuclei. [7] In statistical mechanics, he contributed many ideas to the understanding of ordering, including the concept of 'topological ordering'. [7] Other important results relate to localised electron states in disordered lattices. [2] [7]

Condensed matter physics Branch of physics

Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter, especially the solid and liquid phases which arise from electromagnetic forces between atoms. More generally, the subject deals with "condensed" phases of matter: systems of very many constituents with strong interactions between them. More exotic condensed phases include the superconducting phase exhibited by certain materials at low temperature, the ferromagnetic and antiferromagnetic phases of spins on crystal lattices of atoms, and the Bose–Einstein condensate found in ultracold atomic systems. Condensed matter physicists seek to understand the behavior of these phases by experiments to measure various material properties, and by applying the physical laws of quantum mechanics, electromagnetism, statistical mechanics, and other theories to develop mathematical models.

Cavendish Laboratory

The Cavendish Laboratory is the Department of Physics at the University of Cambridge, and is part of the School of Physical Sciences. The laboratory was opened in 1874 on the New Museums Site as a laboratory for experimental physics and is named after the British chemist and physicist Henry Cavendish. The laboratory has had a huge influence on research in the disciplines of physics and biology.

The Berezinskii–Kosterlitz–Thouless transition is a phase transition of the two-dimensional (2-D) XY model in statistical physics. It is a transition from bound vortex-antivortex pairs at low temperatures to unpaired vortices and anti-vortices at some critical temperature. The transition is named for condensed matter physicists Vadim Berezinskii, John M. Kosterlitz and David J. Thouless. BKT transitions can be found in several 2-D systems in condensed matter physics that are approximated by the XY model, including Josephson junction arrays and thin disordered superconducting granular films. More recently, the term has been applied by the 2-D superconductor insulator transition community to the pinning of Cooper pairs in the insulating regime, due to similarities with the original vortex BKT transition.

Tom Kibble British physicist

Sir Thomas Walter Bannerman Kibble, was a British theoretical physicist, senior research investigator at the Blackett Laboratory and Emeritus Professor of Theoretical Physics at Imperial College London. His research interests were in quantum field theory, especially the interface between high-energy particle physics and cosmology. He is best known as one of the first to describe the Higgs mechanism, and for his research on topological defects. From the 1950s he was concerned about the nuclear arms race and from 1970 took leading roles in promoting the social responsibility of the scientist.

Thouless may refer to:

In crystallography, a disclination is a line defect in which rotational symmetry is violated. In analogy with dislocations in crystals, the term, disinclination, for liquid crystals first used by Frederick Charles Frank and since then has been modified to its current usage, disclination. It is a defect in the orientation of director whereas a dislocation is a defect in positional order.

The hexatic phase is a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles. It is characterized by two order parameters: a short-range positional and a quasi-long-range orientational (sixfold) order. More generally, a hexatic is any phase that contains sixfold orientational order, in analogy with the nematic phase.

He was a condensed matter theorist known for his work on topological insulators, the quantum Hall effect, the quantum spin Hall effect, spintronics, and high-temperature superconductivity. According to the National Academy of Science:

He discovered a new state of matter called topological insulator in which electrons can conduct along the edge without dissipation, enabling a new generation of electronic devices with much lower power consumption. For this ground breaking work he received numerous international awards, including the Buckley Prize, the Dirac Medal and Prize, the Europhysics Prize, the Physics Frontiers Prize and the Benjamin Franklin Medal.

Vadim L'vovich Berezinskii was a Soviet physicist. He was born in Kiev, graduated from Moscow State University in 1959, and worked in Moscow and the Landau Institute for Theoretical Physics. He is famous for having identified the role played by topological defects in the low-temperature phase of two-dimensional systems with a continuous symmetry. His work led to the discovery of the Berezinskii–Kosterlitz–Thouless transition, for which John M. Kosterlitz and David J. Thouless were awarded the Nobel Prize in 2016. He also developed a technique for treating electrons in one-dimensional disordered systems and provided first consistent proof of one-dimensional localization. and predicted negative-gap superconductivity.

The KTHNY-theory describes melting of crystals in two dimensions (2D). The name is derived from the initials of the surnames of John Michael Kosterlitz, David J. Thouless, Bertrand Halperin, David R. Nelson, and A. Peter Young, who developed the theory in the 1970s. It is, beside the Ising model in 2D and the XY model in 2D, one of the few theories, which can be solved analytically and which predicts a phase transition at a temperature .
