Kthny theory
WebDavid James Thouless FRS (/ ˈ θ aʊ l ɛ s /; 21 September 1934 – 6 April 2024) was a British condensed-matter physicist. He was the winner of 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. http://www.cailiaoniu.com/65465.html
