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 controversially 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. Interestingly, the "P-Representation" (now credited as the Glauber–Sudarshan P representation) Glauber used in his paper was actually developed by E. C. George Sudarshan, who was working in the same field. Furthermore, Glauber had criticized Sudarshan's use of classical electromagnetic theory in explaining optical fields, and when his own paper failed to generate any of the typical quantum optics phenomena, he introduced Sudharshan's phase representation- which he had rubbished- as "P-representation", without any credit. 
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 National Laboratory. 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'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.
Awards and honors
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 was elected a Foreign Member of the Royal Society (ForMemRS) in 1997.
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.
Glauber currently lives in Arlington, Massachusetts. Glauber has a son and a daughter, and five grandchildren.
