Indian-American physicist (1924–2021)
Suraj Narayan Gupta (1 December 1924 – 4 July 2021) was an Indian-born American theoretical physicist, notable for his contributions to quantum field theory .
Early life and career
Gupta was born on 1 December 1924 in Punjab , British India .[ 1] He received his M.Sc. from St. Stephen's College, Delhi , and a Ph.D. from the University of Cambridge , and worked at the Dublin Institute for Advanced Studies from 1948 to 1949.[ 2] From 1951 to 1953 he served as ICI Fellow at the University of Manchester .[ 3] In 1953 Gupta joined as a visiting professor at Purdue University and remained there until 1956. From 1956, he served as a professor at Wayne State University in Detroit , where he was a Distinguished Professor of Physics (Emeritus).
Work
Gupta introduced in 1950, simultaneously and independently of Konrad Bleuler , the Gupta–Bleuler quantization of the quantum electrodynamics (QED) that takes the covariant Lorenz gauge condition on an indefinite metric in Hilbert space of states realized.[ 4] From it came some of the first attempts, to derive the equations of general relativity from quantum field theory for a massless spin-2 particle (graviton ).[ 3] [ 5] Similar work has also led Robert Kraichnan in the 1940s (not published until 1955) and later in the 1960s, by Richard Feynman and Steven Weinberg . Later he worked in various areas of quantum field theory and elementary particle physics , including quantum chromodynamics and quarkonium .
Personal life and death
Gupta later resided in Franklin, Michigan .[ 6] He died in West Bloomfield, Michigan on 4 July 2021, at the age of 96.[ 7]
