Jorge A. Swieca

from Wikipedia, the free encyclopedia

Jorge André Swieca (born December 16, 1936 in Warsaw , † December 22, 1980 ) was a Brazilian theoretical physicist.

When Poland was occupied by Germany and the Soviet Union, Swieca's Jewish family fled to Rio de Janeiro via Siberia and Japan. In 1963 he received his doctorate from the University of Sao Paulo under Werner Güttinger (with a thesis that he did at the Max Planck Institute for Physics ). In the 1960s and 1970s he dealt with mathematical quantum field theory, what the Rudolf Haag school called local quantum physics . In 1965 his first publication appeared with Haag, then at the University of Illinois at Urbana-Champaign . In contrast to many representatives of the school, he also tried to find applications in the then current research directions of particle physics. With H. Ezawa, Daniel Kastler and Derek W. Robinson he gave a mathematical justification of the gold stone theorem . He examined various model theories of quantum field theory a. a. by Julian Schwinger and gave a strict treatment of phenomena such as mass production and charge shielding in Abelian gauge theories and pursued ideas to explain confinement.

Swieca was at the University of Sao Paulo from 1959 to 1970. From 1971 he was at the Pontifical Catholic University in Rio and from 1978 at the State University of Sao Carlos in Sao Paulo. He died in 1980 of complications from bypass surgery.

He received the Moinho Santista Prize in 1968 as the second physicist (after Jayme Tiomno ).

He had been married since 1963 and had two children.
