Roy Jay Glauber,
September 1, 1925 – December 26, 2018, was an American theoretical physicist. He
was 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
for Physics "for his contribution to the quantum theory of optical
coherence", with the other half shared by Hohn L Hall and Theodor W
Hansch. 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. His theories are widely used in the field of
quantum optics. In statistical physics, he pioneered the
study of the dynamics of first-order phase transitions since he first
defined and investigated the stochastic dynamics of an Ising model. in a
paper published in 1963.
