Warren Siegel

from Wikipedia, the free encyclopedia

Warren David Siegel (born November 16, 1952 in Flint (Michigan) ) is an American theoretical physicist who is particularly concerned with supersymmetry and string theory.

Siegel studied from 1970 at the University of California, Berkeley (bachelor's degree 1973), where he received his doctorate in 1977 with Martin B. Halpern ( Topics in theoretical particle physics ). As a post-doctoral student he was at Harvard University , at Brandeis University , 1979 to 1980 at the Institute for Advanced Study , 1980 to 1982 at Caltech and until 1985 at Berkeley. From 1985 he was Assistant Professor and from 1987 Professor at the University of Maryland (College Park). He has been Professor at the CN Yang Institute of Theoretical Physics at the State University of New York at Stony Brook since 1988 .

At the end of the 1970s, together with Marcus T. Grisaru and Martin Roček, he introduced improved methods (in superspace) for calculating Feynman diagrams in supersymmetric field theories. With both of them and Sylvester James Gates , he wrote the book Superspace in 1983 . He also introduced a new method of dimensional regularization in supersymmetric perturbation theory (Dimensional Reduction). In the 1980s he was a leader in the development of string field theory. He also wrote a book about this in 1988, which he and a textbook on quantum field theory ( Fields ) made freely available online.
