title:
HANBURY BROWN AND TWISS INTENSITY INTERFEROMETRY:
FROM STARS TO NUCLEI TO ATOMS AND ELECTRONS
abstract:
In the 1950's Hanbury Brown and Twiss showed that one could measure the angular sizes of astronomical radio sources and stars from correlations of signal intensities (not amplitudes) in independent detectors.
Their correlation experiments demonstrating quantum bunching of photons in incoherent light beams were seminal in the development of quantum optics. Since that time the technique of "intensity interferometry" has been applied become in many areas of physics. In high energy nuclear and particle collisions, the technique provides information on the space-time geometry of the collision. The effect is one of the few measurements in elementary particle detection that is sensitive to the wave mechanics of the produced particles. This talk will review the basic physics of intensity interferometry, and its current applications in high-energy nuclear physics, condensed matter,
trapped atomic systems, and electron beams.

(*) Prior to the colloquium, brief introductions to Prof. G. Baym's scientific works will be presented by F. Nori (CEMS and iTHES, RIKEN) and T. Hatsuda (NISHINA and iTHES, RIKEN).
