Abstract
This is a review of Glauber’s asymptotic diffraction theory, in which diffractive scattering is described in terms of interference between semiclassical amplitudes, resulting from a stationary-phase approximation. Typically two such amplitudes are sufficient to accurately describe elastic scattering, but the stationary points are located at complex values of the impact parameter. Their separation controls the interference pattern, and their offsets from the real axis determine the overall fall-off with momentum transfer. Asymptotically, at large momentum transfers, the stationary points move towards singularities of the profile function. I also include some reminiscences from our collaboration.
Highlights
1 Introduction I had the pleasure of working with Professor Roy Glauber on and off for more than 40 years, starting as a postdoctoral fellow at Harvard in 1976, and up to the recent completion of our book [1]
I first give some brief comments to his vita, outline representative elements of our book, before concluding with some reminiscences from our many years of interactions
I found interesting information on the academic ancestors of his PhD supervisor, Julian Schwinger, as well as a list of “children”, basically PhD students. The latter were mostly related to his activity in Quantum Optics, for which he was awarded one half of the 2005 Nobel Prize in Physics, with the citation: “for his contribution to the quantum theory of optical coherence”
