Academic Appointments and Research

Following a postdoctoral research tenure at the Lawrence Berkeley Laboratory, Thouless held various teaching and research positions. He served as the first director of studies in physics at Churchill College, Cambridge, from 1961 to 1965. His subsequent academic career included a professorship in mathematical physics at the University of Birmingham between 1965 and 1978. In 1979, he moved to the United States for a one-year stint as a professor of applied science at Yale University before joining the faculty of the University of Washington in Seattle in 1980.

Scientific Contributions

Thouless specialized in condensed-matter physics, focusing on the many-body problem and superconductivity. His research clarified the concept of rearrangement energy within atomic nuclei and provided mathematical expressions for the moment of inertia in deformed nuclei. He was also instrumental in advancing the understanding of localized electron states within disordered lattices and contributed extensively to statistical mechanics, particularly regarding topological ordering.

Honors and Final Years

His contributions to physics were marked by numerous accolades. He was elected a Fellow of the Royal Society in 1979, the American Physical Society in 1986, and the American Academy of Arts and Sciences. He also held membership in the US National Academy of Sciences. Notable awards include the Maxwell Medal and Prize, the Wolf Prize in Physics, and the Nobel Prize in Physics. Thouless passed away in Cambridge on 6 April 2019.
