Citation | Distinguished for his contribution to the quantum theory of scattering at wavelengths very short compared to the dimensions of the interaction and the scattering objects. These began with his famous derivation of the eclipse effect in scattering by deuterium, ignoring the tensor force which led to its use in a large variety of increasingly complex physically interesting situations, for example, elastic and inelastic scattering of nucleons by complex nuclei and the effect of the tensor force in double scattering by deuterium. Finally he published a seminal volume on his methods in "Lectures in Theoretical Physics, Vol 1" by Interscience in 1959. The Glauber technique has subsequently been applied by a legion of physicists to a host of experiments involving the high-energy scattering of mesons by nuclei and to nuclear processes involving photons and vector mesons. Our knowledge of all high-energy hadron-neutron cross sections stems entirely from this mode of analysis due to him. Equally distinguished for his pioineering work on the foundations of quantum optics. His two first Physical Review papers in this field, which appeared in 1963, set the scene for almost all future work. He bridged the gap between quantum electrodynamics and statistical mechanics, introduced general coherence and correlation functions for the description of arbitrary radiation fields and calculated the photon statistical properties of laser and thermal light which were verified experimentally soon after. The Glauber "P-representation" is a standard tool in papers in quantum optics since his thorough study of the use of quasi-probability distributions. More recently he has made significant contributions to the field quantization in media with arbitrary spatial distribution of the electric susceptibility. His prolific theoretical work also includes the explanation of anomalous gamma-ray spectrum from radiative K-capture by means of the Coulomb Greens function, the introduction of the stochastic Ising model now used, for example, in neural network theory and the proposal for a new class of spin measurements in high-energy nuclear collisions which has led to changes in nearly all known scattering amplitudes. |
