From Coherent Tunneling to Relaxation is an impressive review of ten years of progress in our understanding of interacting tunneling systems. The dielectric and elastic response of (111) off-center impurities in alkalide halides is investigated in detail and the coherent motion of an impurity pair is discussed in view of recently observed rotary echoes. The low-temperature properties of defect crystals with an impurity concentration higher than 100 ppm are reviewed and the dipolar interaction is shown to drive the cross-over to relaxational dynamics. This comprehensive presentation of the theory is illustrated by experimental data for lithium, cyanide, and hydroxyl impurities in various host crystals. This monograph is an ideal reference book for scientists working with defect crystals and glasses

The Advanced Study Institute (AS!) considered a number offacets of the very rapidly advancing field of theoretical and experimental aspects of ultrashort processes in condensed matter. Common threads exist between a series of example cases. One major subgroup of topics involves the ultrashort dynamics of excitations of various "particles" produced through the interactions of condensed matter with ultrashort duration laser light. Examples ofthe excitations include electronic and hole carriers, electron-hole plasma, phonons, vibrons and rotons, two phonon states, and excitons. Experimentation on the dynamics of such excitations, are carried out in the bulk, at surfaces, in thin films, and in quantum wells. The dynamical steps which the excitations usually undergo include photo-excitation, local thermalization, particle-particle interaction, particle phonon interactions and eventual return to true thermal equilibrium. This ASI was organized to benefit particularly advanced graduate students, specifically, those near the end of their Ph.D. thesis projects, and also for postdoctoral scholars already active in the field. The overall organizational goal was centered around a set oftutorially based lectures intermingled with full scale discussion periods of equal time and importance as the lectures. The general discussion periods were designed to offer to the participants ample time to ask detailed questions and to make comments and contributions of their own. In order to complete the involvement of the participants a full length poster session was also held. A representative set of abstracts of these posters appear as an Appendix to the lectures.

Surveys the contemporary concepts and theoretical and experimental results of tunneling processes. Examines from a unified viewpoint not only chemical reactions but also other physical physicochemical and biological phenomena in which the tunneling effect is of great importance. Covers the general ideas of tunneling, the low temperature chemical reactions that manifest tunneling mechanisms, tunneling effects in amorphous materials, quantum diffusion and surface phenomena in quantum crystals, hopping diffusion and tunneling scavenging of electrons, and tunneling effects in biological systems.

In 2001, the Nobel Foundation celebrated the 100th anniversary of the first Nobel Prize, and all previous Nobel laureates were invited to attend the Nobel ceremonies in Stockholm. This gave an excellent opportunity for arranging jubilee symposia with topics that would attract several of the laureates. The chosen subject of ?Condensation and Coherence in Condensed Systems? attracted sixteen Nobel laureates and another thirty-five leading scientists.The idea was to bring scientists together from several related subdisciplines: atomic physics, quantum optics, and condensed matter physics, for cross-breeding of ideas, concepts, and experience. Subjects like phase transitions in strongly coupled systems, Bose-Einstein condensation in weakly coupled systems, macroscopic quantum phenomena, coherence in mesoscopic structures, and quantum information were intensively discussed from different points of view. Coherence phenomena in condensed systems were emphasized. A special session was devoted to the emerging field of quantum computing, with experimental and theoretical results reported for different types of qu-bits. The 2001 Nobel Prize awarded to Eric Cornell, Wolfgang Ketterle, and Carl Wieman, ?for the achievement of Bose-Einstein condensation in dilute gases of alkali atoms, and for early fundamental studies of the properties of the condensates,? gave an extra flavor to the theme of the Centennial Symposium.

This volume is an outgrowth of the Second International Workshop on Macroscopic Quantum Coherence and Computing held in Napoli, Italy, in June 2000. This workshop gathered a number of experts from the major Universities and Research Institutions of several countries. The choice of the location, which recognizes the role and the traditions of Naples in this field, guaranteed the participants a stimulating atmosphere. The aim of the workshop has been to report on the recent theoretical and experimental results on the macroscopic quantum coherence of macroscopic systems. Particular attention was devoted to Josephson devices. The correlation with other atomic and molecular systems, exhibiting a macroscopic quantum behaviour, was also discussed. The seminars provided both historical overview and recent theoretical ground on the topic, as well as information on new experimental results relative to the quantum computing area. The first workshop on this topic, held in Napoli in 1998, has been ennobled by important reports on observations of Macroscopic Quantum Coherence in mesoscopic systems. The current workshop proposed, among many stimulating results, the first observations of Macroscopic Quantum Coherence between macroscopically distinct fluxoid states in rf SQUIDs, 20 years after the Leggett's proposal to experimentally test the quantum behavior of macroscopic systems. Reports on observations of quantum behaviour in molecular and magnetic systems, small Josephson devices, quantum dots have also been particularly stimulating in view of the realization of several possible q-bits.

In recent years the physics of disordered systems has been one of the most active and fruitful areas of research in condensed matter science. In contrast to the considerable attention paid by conferences, schools and workshops to the static and structural aspects of glasses, there has been no forum devoted primarily to the dynamic and energetic aspects of amorphous solids. The NATO Workshop on Coherence and Energy Transfer in Glasses was organized to address this deficiency. The intent was to bring together in an intense and interactive environment, experts in several rather disparate subfields relating to the dynamics and energetics of disordered systems. This volume represents the Proceedings of that Workshop, which took place in September 1982 at Clare College of Cambridge University. Forty-three scientists from eight NATO countries participated. These included representatives from universities and industrial laboratories, as well as government research institutions. The meeting was organized into eight formal sessions and one informal session devoted entirely to unstructured discussion. Each formal session featured two comprehensive lectures. An additional 60 to 90 minutes was devoted in each session to discussions and contributions related to the lectures. Since only about 60% of the session time was devoted to formal presentations, the discussions formed an equally important part of the workshop. The chairmen and discussion leaders - as well as the workshop participants themselves - brought forth lively and illuminating discussions for each session.
