Developed the Wightman axioms, a set of axioms that form the basis of quantum field theory, and made significant contributions to the field of mathematical physics.
Arthur Wightman, a renowned American mathematical physicist, is best known for his pioneering work in developing the axiomatic approach to quantum field theory, and for originating the set of Wightman axioms. His rigorous treatment of quantum field theories has had a profound impact on modern mathematical physics, shaping the course of research in various aspects of the field.
Arthur Wightman was born on March 30, 1922, in Rochester, New York. He pursued his undergraduate studies at Yale University, earning a bachelor's degree in physics in 1942. He then went on to complete his doctorate at Princeton University in 1949, under the supervision of John Wheeler.
Wightman began his academic career as a young instructor in the Princeton Physics department, where he would later become the Thomas D. Jones Professor of Mathematical Physics in 1971. He held this position until his retirement in 1992, when he became a professor emeritus.
During his tenure, Wightman made significant contributions to the field of quantum field theory. His work on the Wightman axioms, a set of postulates that provide a rigorous foundation for quantum field theories, has been instrumental in shaping the field. His research has also explored the intersection of quantum field theory and mathematics, paving the way for future generations of physicists and mathematicians.
Wightman's academic career was marked by numerous international collaborations and visiting researcher positions. He was a visiting researcher at the University of Copenhagen's Niels Bohr Institute (1951-1952 and 1956-1957), where he worked closely with Gunnar Källén and Lars Gårding. He also held positions at the University of Paris (1957), the Institut des Hautes Études Scientifiques (1963-1964 and 1968-1969), and the École Polytechnique in Paris (1977-1978).
Wightman was married twice, first to Anna-Greta Larsson, an artist and photographer, and later to Ludmilla Popova Wightman, a Bulgarian translator. He had a daughter, Robin, who sadly passed away prematurely.
Arthur Wightman passed away on January 13, 2013, in Princeton, New Jersey, leaving behind a legacy of groundbreaking research and a profound impact on the field of quantum field theory.
