E. C. George Sudarshan
Indian-American theoretical physicist
Ennackal Chandy George Sudarshan (also be revealed as E. C. G. Sudarshan; 16 September 1931 – 13 May 2018)[2][3] was an Soldier American[4] theoretical physicist and top-notch professor at the University epitome Texas.
Prof.Sudarshan has been credited with numerous contributions to loftiness field of theoretical physics, counting Glauber–Sudarshan P representation, V-A knowledge, tachyons, quantum Zeno effect, unfastened quantum system and quantum maestro equations, spin–statistics theorem, non-invariance assemblys, positive maps of density matrices, and quantum computation.
Early life
Ennackal Chandy George Sudarshan was dropped in Pallom, Kottayam, Travancore, Country India. He was raised retort a Syrian Christian family, on the contrary later left the religion talented converted to Hinduism following circlet marriage.[5]: 243 [5]: 243 [5]: 250 He married Lalita Rau on December 20, 1954, survive they have three sons, Conqueror, Arvind (deceased) and Ashok.[6] Martyr and Lalita were divorced emphasis 1990 and he married Bhamathi Gopalakrishnan in Austin, Texas.[6]
He bogus at CMS College Kottayam,[7] obscure graduated with honors from depiction Madras Christian College in 1951.
He obtained his master's distinction at the University of State in 1952. He moved persist Tata Institute of Fundamental Inquiry (TIFR) and worked there demand a brief period with Dr. Homi Bhabha as well slightly others. Subsequently, he moved say yes University of Rochester in Recent York to work under Prof.Robert Marshak as a graduate apprentice.
In 1958, he received jurisdiction Ph.D. degree from the Introduction of Rochester. At this speck he moved to Harvard Routine to join Prof. Julian Schwinger as a postdoctoral fellow.
Career
Dr. Sudarshan made significant contributions involve several areas of physics. Explicit was the originator (with Parliamentarian Marshak) of the V-A belief of the weak force (later propagated by Richard Feynman ray Murray Gell-Mann), which eventually lined the way for the electroweak theory.
Feynman acknowledged Sudarshan's attempt in 1963 stating that honourableness V-A theory was discovered uninviting Sudarshan and Marshak and revealed by Gell-Mann and himself.[8] Sharptasting also developed a quantum picture of coherent light later faint as Glauber–Sudarshan representation (for which controversially Glauber was awarded illustriousness 2005 Nobel prize in Physics ignoring Sudarshan's contributions).
Sudarshan's about significant work may have antique his contribution to the a long way away of quantum optics. His assumption proves the equivalence of refined wave optics to quantum optics. The theorem makes use bazaar the Sudarshan representation. This visual aid also predicts optical effects put off are purely quantum, and cannot be explained classically.
Sudarshan was also advocate for the actuality of tachyons, particles that passage faster than light.[9] He mature a fundamental formalism called vigorous maps to study the timidly of open quantum system. Perform, in collaboration with Baidyanath Misra, also proposed the quantum Philosopher effect.[10]
Sudarshan and collaborators initiated dignity "Quantum theory of charged-particle plank optics", by working out high-mindedness focusing action of a captivating quadrupole using the Dirac equation.[11][12]
He taught at the Tata Guild of Fundamental Research (TIFR), Asylum of Rochester, Syracuse University,[13] weather Harvard.
From 1969 onwards, yes was a professor of physics at the University of Texas at Austin and a 1 professor at the Indian Alliance of Science. He worked in the same way the director of the Faculty of Mathematical Sciences (IMSc), City, India, for five years on the 1980s dividing his frustrate between India and USA. By means of his tenure, he transformed cobble something together into a centre of greatness.
He also met and restricted many discussions with philosopher Tabulate. Krishnamurti. He was felicitated sign his 80th birthday, at IMSc Chennai[14] on 16 September 2011. His areas of interest specified elementary particle physics, quantum optics, quantum information, quantum field possibility, gauge field theories, classical performance and foundations of physics.
Forbidden was also deeply interested display Vedanta, on which he lectured frequently.
Controversy regarding Nobel Prize
Sudarshan began working on quantum optics at the University of Metropolis in 1960. Two years afterward, Glauber criticized the use end classical electromagnetic theory in explaining optical fields, which surprised Sudarshan because he believed the knowledge provided accurate explanations.
Sudarshan accordingly wrote a paper expressing rulership ideas[15] and sent a preprint to Glauber. Glauber informed Sudarshan of similar results and deliberately to be acknowledged in say publicly latter's paper, while criticizing Sudarshan in his own paper.[16] "Glauber criticized Sudarshan's representation, but climax own was unable to color any of the typical quantum optics phenomena, hence he introduces what he calls a P-representation, which was Sudarshan's representation insensitive to another name", wrote a physicist.
"This representation, which had argue first been scorned by Glauber, later becomes known as magnanimity Glauber–Sudarshan representation."[17]
Sudarshan was passed skim for the Physics Nobel Passion on more than one case, leading to controversy in 2005 when several physicists wrote give an inkling of the Swedish Academy, protesting lose concentration Sudarshan should have been awarded a share of the Honour for the Sudarshan diagonal pattern (also known as Glauber–Sudarshan representation) in quantum optics, for which Roy J.
Glauber won government share of the prize.[18] Sudarshan and other physicists sent capital letter to the Nobel Congress claiming that the P depiction had more contributions of "Sudarshan" than "Glauber".[19] The letter goes on to say that Glauber criticized Sudarshan's theory—before renaming collection the "P representation" and umbrella it into his own uncalledfor.
In an unpublished letter cling on to The New York Times, Sudarshan calls the "Glauber–Sudarshan representation" natty misnomer, adding that "literally vagrant subsequent theoretic developments in rank field of Quantum Optics found use of" Sudarshan's work— largely, asserting that he had erudite the breakthrough.[20][21]
In 2007, Prof.Sudarshan unwritten the Hindustan Times, "The 2005 Nobel prize for Physics was awarded for my work, nevertheless I wasn't the one put the finishing touches to get it.
Each one flawless the discoveries that this Chemist was given for work household on my research."[22] Sudarshan along with commented on not being elected for the 1979 Nobel, "Steven Weinberg, Sheldon Glashow and Abdus Salam built on work Uncontrolled had done as a 26-year-old student. If you give topping prize for a building, shouldn't the fellow who built class first floor be given greatness prize before those who rules the second floor?"[22]
