Suraj N. Gupta

from Wikipedia, the free encyclopedia

Suraj Narayan Gupta (born December 1, 1924 in Haryana , Punjab , British India ) is an Indian-American theoretical physicist who deals with quantum field theory.

Gupta received his doctorate in 1951 from Cambridge University (Master's degree in 1946, St. Stephens College) and was at the Institute for Advanced Study in Dublin in 1948/9 . He was also at the Argonne National Laboratory and the National Research Council of Canada. From 1951 to 1953 he was an ICI fellow at the University of Manchester . 1953 to 1956 he was visiting professor at Purdue University and from 1956 professor at Wayne State University in Detroit . There he is Distinguished Professor of Physics.

In 1950, Gupta introduced the Gupta-Bleuler quantization method into quantum electrodynamics (QED) simultaneously with and independently of Konrad Bleuler , which implements the covariant Lorentz gauge condition via an indefinite metric in the Hilbert space of states. He was also responsible for some of the first attempts to derive the equations of general relativity from quantum field theory for a massless spin 2 particle (graviton), which is coupled to a obtained matter-energy-momentum tensor. Similar work was also carried out by Robert Kraichnan in the 1940s (published only in 1955) and later in the 1960s by Richard Feynman , Steven Weinberg . Later he dealt with various areas of quantum field theory and elementary particle physics, u. a. Quantum Chromodynamics and Quarkonium .

He is a Fellow of the American Physical Society and the Indian National Academy of Sciences.
