This Advanced Study Institute (ASI) brought together two distinct ·"schools of approach" to Quantum Electrodynamics (QED) in the presence of intense, external, electromagnetic fields, in an effort to lay a joint foundation for a needed theoretical explanation of the sharp e+ e- "resonances" observed in the scattering of very heavy IOns. These (GSI/Darmstadt) experiments, whose history, latest reconfirmations, and most recent data were presented in three opening sessions (Bokemeyer, Koenig), show a smooth background of positron (e+) production, as a function of e+ kinetic energy. Superimposed upon this background are four very sharp peaks, of narrow widths (~ 30 KeV) and of clear experimental significance ('" 5 standard deviations). Most ofthese peaks correspond to sharp, essentially back-to-back electron-positron emission in the ions' center of mass. Following the approach of "supercritical" potential theory (SPT), where the total ionic charge unit Z satisfies Z > 137, it has been possible to provide a detailed and apparently correct understanding of the smooth e+ e- background; a coherent description of different facets of this approach, emphasizing the nature of the charged, supercritical vacuum, was described by the authors responsible for the invention of SPT (Greiner, Muller, Rafelski). In addition, predictions for related phenomena were outlined by other lecturers using the SPT approach (Bawin, Soff, SsJrensen).

Significant advances have occurred in the field since the previous edition, including advances in light squeezing, single photon optics, phase conjugation, and laser technology. The laser is essentially responsible for nonlinear effects and is extensively used in all branches of science, industry, and medicine.

This should be a useful reference for anybody with an interest in quantum theory.

“A compelling, enjoyable, and widely accessible exploration of one of the most fundamental scientific issues of our age” (Brian Greene, author of The Elegant Universe). In The Hole in the Universe, an award-winning science writer “provides an illuminating slant on physics and mathematics by exploring the concept of nothing” (Scientific American). Welcome to the world of cutting-edge math, physics, and neuroscience, where the search for the ultimate vacuum, the point of nothingness, the ground zero of theory, has rendered the universe deep, rich, and juicy. Every time scientists and mathematicians think they have reached the ultimate void, something new appears: a black hole, an undulating string, an additional dimension of space or time, repulsive anti-gravity, universes that breed like bunnies. Cole’s exploration at the edge of everything is “as playfully entertaining as it is informative” (San Jose Mercury News). “A strong and sometimes mind-blowing introduction to the edges of modern physics.” —Salon.com “Comprising an expansive set of topics from the history of numbers to string theory, the big bang, even Zen, the book’s chapters are broken into bite-sized portions that allow the author to revel in the puns and awkwardness that comes with trying to describe a concept that no one has fully grasped. It is an amorphous, flowing, mind-bending discussion, written in rich, graceful prose. As clear and accessible as Hawking’s A Brief History of Time, this work deserves wide circulation, not just among science buffs.” —Publishers Weekly, starred review “Here we have the definitive book about nothing, and who would think that nothing could be so interesting . . . not only accessible but compelling reading.” —St. Louis Post-Dispatch
