Summary: Quantum chaos is becoming a very wide field that ranges from experiments to theoretical physics and purely mathematical issues. In view of this grand span, Nobel Symposium 116 focused on experiments and theory, and attempted to encourage interplay between them. There was emphasis on the interdisciplinary character of the subject, involving a broad range of subjects in physics, including condensed matter physics, nuclear physics, atomic physics and elementary particle physics. The physics involved in quantum chaos has much in common with acoustics, microwaves, optics, etc., and therefore the symposium also covered aspects of wave chaos in this broader sense. The program was structured according to the following areas: manifestations of classical chaos in quantum systems; transport phenomena; quantal spectra in terms of periodic orbits; semiclassical and random matrix approaches; quantum chaos in interacting systems; chaos and tunneling; wave-dynamic chaos. This important book constitutes the proceedings of the symposium. Contents: After-Dinner Speech (M C Gutzwiller); Spectral Twinkling: A New Example of Singularity-Dominated Strong Fluctuations (Summary) (M Berry); Ground State Spin and Coulomb Blockade Peak Motion in Chaotic Quantum Dots (J A Folk et al.); Quantum Chaos and Transport Phenomena in Quantum Dots (A S Sachrajda); Chaos in Quantum Ratchets (H Linke et al.); Non-Universality of Chaotic Classical Dynamics: Implications for Quantum Chaos (M Wilkinson); Chaos and Interactions in Quantum Dots (Y Alhassid); Stochastic Aspects of Many-Body Systems: The Embedded Gaussian Ensembles (H A Weidenmüller); Effect of Symmetry Breaking on Statistical Distributions (G E Mitchell & J F Shriner, Jr.); Quantum Chaos and Quantum Computers (D L Shepelyansky); Disorder and Quantum Chromodynamics - Non-Linear σ Models (T Guhr & T Wilke); Correlation BetweenSummary: Periodic Orbits and Their Rôle in Spectral Statistics (M Sieber & K Richter); Neutron Stars and Quantum Billiards (A Bulgac & P Magierski); Tunneling and Chaos (S Tomsovic); Relaxation and Fluctuations in Quantum Chaos (G Casati); Scars and Other Weak Localization Effects in Classically Chaotic Systems (E J Heller); Classically-Forbidden Processes in Photoabsorption Spectra (J B Delos et al.); Wave Dynamical Chaos: An Experimental Approach in Billiards (A Richter); Acoustic Chaos (C Ellegaard et al.); Wave-Chaotic Optical Resonators and Lasers (A D Stone); Angular Momentum Localization in Oval Billiards (J U Nöckel); Chaos and Time-Reversed Acoustics (M Fink); and other papers.
