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

In disordered solids, two-level atomic-tunneling systems are present in large quantity. Only recently, superconducting qubits opened a door for a detection and individual coherent manipulation of such microscopic quantum systems. We succeeded to tune the resonance frequencies of these systems by applying external strain on the qubit chip. Moreover, we observed and analyzed the interaction between two coupled tunneling systems.

A review of principle topical issues on the basic science of glasses and amorphous thin-films. It also includes select applications of these materials in current and evolving technologies, including optical recording, imaging, solar cells, battery technology and field-emission displays. The glass systems of interest include oxides, chalcogenides and chalcohalides of the group III, IV and V elements, as well as amorphous thin-films of the group IV elements. Glass formation in covalent melts can be understood in terms of new ideas based on constraint counting algorithms which have led to the fragile-strong classification and to the concept of rigidity transition. Vibrational excitations and characterization of the atomic scale structure at various length scales are addressed by an array of experimental probes, including X-ray and neutron scattering, Brillouin scattering, Raman scattering and infrared reflectance, solid state nuclear magnetic resonance, nuclear quadrupole resonance and Mossbauer spectroscopy. Chapters are also devoted to the physics of electronic transport in amorphous materials, to the physics of tunnelling states in crystalline and amorphous solids, and the physics of light-induced effects in glasses. In addition, a chapter is devoted to the rapidly-evolving field of numerical simulations of disordered systems by computer modelling. Each of these topics is discussed by experts who have made contributions to the field.

This book has its origins in the 1982 Spring College held at the Interna tional Centre for Theoretical Physics, Miramare, Trieste. The primary aim is to give a broad coverage of liquids and amorphous solids, at a level suitable for graduate students and research workers in condensed-matter physics, physical chemistry, and materials science. The book is intended for experimental workers with interests in the basic theory. While the topics covered are many, it was planned to place special emphasis on both static structure and dynamics, including electronic transport. This emphasis is evident from the rather complete coverage of the determination of static structure from both diffraction experiments and, for amorphous solids especially, from model building. The theory of the structure of liquids and liquid mixtures is then dealt with from the standpoint of, first, basic statistical mechanics and, subsequently, pair potentials constructed from the electron theory of simple metals and their alloys. The discussion of static structure is completed in two chapters with rather different emphases on liquid surfaces and interfaces. The first deals with the basic statistical mechanics of neutral and charged interfaces, while the second is concerned with solvation and double-layer effects. Dynamic structure is introduced by a comprehensive discussion of single-particle motion in liquids. This is followed by the structure and dynamics of charged fluids, where again much basic statistical mechanics is developed.
