E. C. George Sudarshan
Chandy George Sudarshan Ennackal (often ECG Sudarshan, born September 16, 1931 in Pallam, Kottayam District, Kerala ) is an Indian theoretical physicist.
Life
Sudarshan studied at Madras Christian College (1948-1951) and the University of Madras, where in 1952 he received his master's degree. 1951 to 1955 he was at the Tata Institute of Fundamental Research Homi Jehangir Bhabha with. In 1955 he went to the University of Rochester in New York, where he received his doctorate with Robert Marshak 1958. After that, he was from 1957 to 1959 Corporation Fellow at Harvard University (with Julian Schwinger ), from 1959 assistant professor and since 1961 associate professor at Rochester University and from 1964 professor at Syracuse University, where he was director of the research program elementary particle physics. From 1969 he was professor at the University of Texas at Austin ( 1970-1991 Director of the Center for Particle Theory ) and 1971-1991 senior professor at the Indian Institute of Science, Bangalore. During the 1980s he was also five years director of the Institute of Mathematical Sciences in Chennai.
In 2007 he received the Padma Vibhushan award high Indian and Padma Bhushan in 1974. In 1970 he received the C.V. Raman Award, 1977, the Bose Medal, the 1986 Physics Prize of the Third World Academy of Sciences and in 2006 the Majoranapreis. He is a member of the Indian and Ukrainian Academy of Sciences and the Third World Academy of Sciences. He is a multiple honorary doctorates, including the Universities of Madras and Delhi.
Work
Sudarshan delivered fundamental contributions in several areas of physics. Regardless of Richard Feynman and Murray Gell-Mann, he developed with Robert Marshak the VA theory of weak interactions, which prepared the unified gauge theory of the electroweak interaction, and independent of Roy Glauber Sudarshan - Glauber representation of coherent waves in quantum optics. He also developed one of the first a theory of tachyons and led with a Baidyanaith Misra the quantum Zeno effect. From Sudarshan come many other contributions to mathematical physics, quantum field theory (including theories with indefinite metric ), the formalism of quantum mechanics and classical dynamics. He was, for example new evidence of the spin-statistics theorem, proved a theorem on the triviality of Hamiltonian mechanics of a fixed number of particles in the follow particles specially - relativistic world lines, and treated the stochastic dynamics (open ) quantum systems (for example, in the measurement process, or in the decay of a quantum state ).
Sudarshan is also interested in Indian philosophy ( Vedanta ), which he also lectures.
