Roy Jay Glauber (born September 1, 1925) is an American theoretical physicist. He is the Mallinckrodt Professor of Physics at Harvard University and Adjunct Professor of Optical Sciences at the University of Arizona. Born in New York City, he was awarded one half of the 2005 Nobel Prize in Physics "for his contribution to the quantum theory of optical coherence", with the other half shared by John L. Hall and Theodor W. Hänsch. In this work, published in 1963, he created a model for photodetection and explained the fundamental characteristics of different types of light, such as laser light (see coherent state) and light from light bulbs (see blackbody). His theories are widely used in the field of quantum optics.
Glauber was born in 1925 in New York City. He was a member of the 1941 graduating class of the Bronx High School of Science, and went on to do his undergraduate work at Harvard University. After his sophomore year he was recruited to work on the Manhattan Project, where (at the age of 18) he was one of the youngest scientists at Los Alamos. His work involved calculating the critical mass for the atom bomb. After two years at Los Alamos, he returned to Harvard, receiving his bachelor's degree in 1946 and his PhD in 1949.
Glauber has received many honors for his research, including the Albert A. Michelson Medal from the Franklin Institute in Philadelphia (1985), the Max Born Award from the Optical Society of America (1985), the Dannie Heineman Prize for Mathematical Physics from the American Physical Society (1996), and the 2005 Nobel Prize in Physics. On 22 April 2008, Professor Glauber was awarded the 'Medalla de Oro del CSIC' ('CSIC's Gold Medal') in a ceremony held in Madrid, Spain.
He currently lives in Arlington, Massachusetts, and is the Mallinckrodt Professor of Physics at Harvard University, where both past and present students enthusiastically praised his teaching to Harvard Crimson reporters. On April 15, 2010 police in Arlington caught a man they suspected of breaking into Glauber's home; he was convicted of break and enter, but it was only a replica of Glauber's Nobel Prize that was stolen. Glauber has a son and a daughter, and five grandchildren.
Glauber's recent research has dealt with problems in a number of areas of quantum optics, a field which, broadly speaking, studies the quantum electrodynamical interactions of light and matter. He is also continuing work on several topics in high-energy collision theory, including the analysis of hadron collisions, and the statistical correlation of particles produced in high-energy reactions.
Specific topics of his current research include: the quantum mechanical behavior of trapped wave packets; interactions of light with trapped ions; atom counting-the statistical properties of free atom beams and their measurement; algebraic methods for dealing with fermion statistics; coherence and correlations of bosonic atoms near the Bose–Einstein condensation; the theory of continuously monitored photon counting-and its reaction on quantum sources; the fundamental nature of “quantum jumps”; resonant transport of particles produced multiply in high-energy collisions; the multiple diffraction model of proton-proton and proton-antiproton scattering.
For many years before winning his Nobel Prize, Glauber was familiar to audiences of the Ig Nobel Prize ceremonies, where he took a bow each year as "Keeper of the Broom," sweeping the stage clean of the paper airplanes that have traditionally been thrown during the event. He missed the 2005 event, though, as he was being awarded his real Nobel Prize at the time.
Controversy regarding Nobel Prize
E. C. George Sudarshan ,an Indian theoretical physicist and a professor at the University of Texas began working on quantum optics at the University of Rochester in 1960. Two years later, Glauber criticized the use of classical electromagnetic theory in explaining optical fields, which surprised Sudarshan because he believed theory provided accurate explanations. Sudarshan subsequently wrote a paper expressing his ideas and sent a preprint to Glauber. Glauber informed Sudarshan of similar results and asked to be acknowledged in the latter’s paper, while criticizing Sudarshan in his own paper. “Glauber criticized Sudarshan’s representation, but his own was unable to generate any of the typical quantum optics phenomena, hence he introduces what he calls a P-representation, which was Sudarshan’s representation by another name,” wrote a physicist . “This representation, which had at first been scorned by Glauber, later becomes known as the Glauber-Sudarshan representation.”
Sudarshan has been passed over for the Physics Nobel Prize on more than one occasion, leading to controversy in 2005 when several physicists wrote to the Swedish Academy, protesting that Sudarshan should have been awarded a share of the Prize for the Sudarshan diagonal representation (also known as Sudarshan-Glauber representation) in quantum optics, for which Roy J. Glauber won his share of the prize.
