Roy J. Glauber

Physics

Physicist, Roy Glauber, won half the Nobel Prize in physics in 2005 "for his contribution to the quantum theory of optical coherence.” The other half was awarded to John L. Hall and Theodor W. Hänsch "for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique. Roy Glauber studied physics, and in particular quantum optics. He theoretically described electromagnetic radiation (coherent and incoherent) in fully quantum mechanical terms. He also mathematically proved the nearly classical behavior of a system of coherent, coupled quantum oscillators.
