Book Description
Drop a pebble in a pond and the results are predictable: circular waves flow from the point of impact. Hit a point on a crystalline solid, however, and the expanding waves are highly nonspherical; the elasticity of a crystal is anisotropic. This book provides a fresh look at the vibrational properties of crystalline solids, elucidated by new imaging techniques. From the megahertz vibrations of ultrasound to the near-terahertz vibrations associated with heat, the underlying elastic anisotropy of the crystal asserts itself. Phonons are elementary vibrations that affect many properties of solids--thermal, electrical, and magnetic. This text covers the basic theory and experimental observations of phonon propagation in solids. Phonon imaging techniques provide physical insights into such topics as phonon focusing, lattice dynamics, and ultrasound propagation. Scattering of phonons from interfaces, superlattices, defects, and electrons are treated in detail. The book includes many striking and original illustrations.

Book Description
Phonons are always present in the solid state even at an absolute temperature of 0 K where zero point vibrations still abound. Moreover, phonons interact with all other excitations of the solid state and, thereby, influence most of its properties. Historically experimental information on phonon transport came from measurements of thermal conductivity. Over the past two decades much more, and much more detailed, information on phonon transport and on many of the inherent phonon interaction processes have come to light from experiments which use nonequilibrium phonons to study their dynamics. The resultant research field has most recently blossomed with the development of ever more sophisticated experimental and theoretical methods which can be applied to it. In fact, the field is moving so rapidly that new members of the research community have difficulties in keeping up to date. This NATO Advanced Study Institute (ASI) was organized with the objective of overcoming the information barrier between those expert in the field and those who are new to it. Thus it was decided to (i) organize a set of tutorially based lectures covering most of the important facets in the field, and (ii) to produce an Institute proceedings which would serve both as the first general textbook, as well as a valuable reference book, for this field of knowledge.

Book Description
This book presents a comprehensive description of phonons and their interactions in systems with different dimensions and length scales. Internationally-recognized leaders describe theories and measurements of phonon interactions in relation to the design of materials with exotic properties such as metamaterials, nano-mechanical systems, next-generation electronic, photonic, and acoustic devices, energy harvesting, optical information storage, and applications of phonon lasers in a variety of fields. The emergence of techniques for control of semiconductor properties and geometry has enabled engineers to design structures in which functionality is derived from controlling electron behavior. As manufacturing techniques have greatly expanded the list of available materials and the range of attainable length scales, similar opportunities now exist for designing devices whose functionality is derived from controlling phonon behavior. However, progress in this area is hampered by gaps in our knowledge of phonon transport across and along arbitrary interfaces, the scattering of phonons with crystal defects, interface roughness and mass-mixing, delocalized electrons/collective electronic excitations, and solid acoustic vibrations when these occur in structures with small physical dimensions. This book provides a comprehensive description of phonons and their interactions in systems with different dimensions and length scales. Theories and measurements of phonon interactions are described in relation to the design of materials with exotic properties such as metamaterials, nano-mechanical systems, next-generation electronic, photonic, and acoustic devices, energy harvesting, optical information storage, and applications of phonon lasers in a variety of fields.

Book Description
This book constitutes the proceedings of the 19th International Symposium on Acoustical Imaging at the Ruhr-University Bochum, Germany during April 3 -5, 1991. It was the first time that the symposium was held in Europe after major political changes happened in that area. The freedom to travel for all people from eastern European countries was an obvious reason for the great numbers of sub mitted abstracts and for numerous conference participants. 193 of 239 submitted contributions from 29 countries were accepted for presentation by authors from USA (13%), Canada (2%), Japan (7%), Peoples Republic of China (7%), United Kingdom (4%), France (7%), Italy (3%), Poland (4%), Soviet Union (7%), Germany (28%) and other countries (18%). 283 scientists from 29 countries attended the conference representing the interdisciplinary field between mathematics, physics, engineering and medicine. 151 papers were available for publication in this proceedings covering the topics 1. Mathematics and Physics of Acoustical Imaging 2. Components and Systems 3. Applications in Medicine and Biology 4. Applications in Nondestructive Testing 5. Remote Sensing Applications 6. Industrial Applications A relative large number of contributions on acoustical microscopy was included in the conference program within topics 3 and 4. Also, papers on "non-traditional" acoustical imaging subjects, e. g. on phonon imaging and on remote sensing in the atmosphere, have broadened the scope of the conference. The success and stimulation of the conference and of the papers presented in this volume is owed, of course to the authors and participants.

Book Description
This volume contains the proceedings of the Fifth International Confer ence on Phonon Scattering in Condensed Matter held June 2-6, 1986 at the University of Illinois at Urbana-Champaign. The preceding confer ences were held at St. Maxime and Paris in 1972, at the University of Nottingham in 1975, at Brown University in 1979, and at the University of Stuttgart in 1983. The Illinois conference dealt with both traditional and newly developing topics in the area of phonon scattering. Papers were presented on phonon scattering in glassy and crystalline dielectrics, semi conductors, metals (both normal and superconducting), and in the areas of phonon imaging, large wave vector phonons, optical techniques and new experimental methods. The 12 invited papers and 100 contributed papers were presented by the 125 scientists from 14 countries. A citation was presented to Professor Paul Klemens of the University of Connecticut for his pioneering contributions to the physics of phonon scattering in solids.

Book Description
This volume contains the proceedings of the Seventh International Conference on Phonon Scattering in Condensed Matter held August 3-7, 1992, at Cornell University in Ithaca, NY, USA. The preceding conferences were held at: St. Maxime and Paris (France) 1972, Nottingham (UK) 1975, Providence (USA) 1979, Stuttgart (Germany) 1983, Urbana (USA) 1986, and Heidelberg (Germany) 1989. The Heidelberg conference was held jointly with the Third International Con ference on Phonon Physics. The next conference, to be held in August, 1995, in Sapporo, Japan, and hosted by Professor T. Nakayama and his colleagues, will also be such a joint conference. This conference was attended by 227 scientists from 27 countries, and covered all aspects of phonon scattering in condensed matter, ranging from the more traditional topics of thermal conductivity, Kapitza resistance, and ballistic phonon propagation to the recently added topics, such as electron-phonon interaction in high-T c superconductors, the use of phonons in particle detection, and phonons in confined geometries. The 207 papers arranged in 11 chapters in this volume are a cross section of the present activities in the quite obviously vibrant field of phonons and their interactions.

Book Description
There have been few books devoted to the study of phonons, a major area of condensed matter physics. The Physics of Phonons is a comprehensive theoretical discussion of the most important topics, including some topics not previously presented in book form. Although primarily theoretical in approach, the author refers to experimental results wherever possible, ensuring an ideal book for both experimental and theoretical researchers. The author begins with an introduction to crystal symmetry and continues with a discussion of lattice dynamics in the harmonic approximation, including the traditional phenomenological approach and the more recent ab initio approach, detailed for the first time in this book. A discussion of anharmonicity is followed by the theory of lattice thermal conductivity, presented at a level far beyond that available in any other book. The chapter on phonon interactions is likewise more comprehensive than any similar discussion elsewhere. The sections on phonons in superlattices, impure and mixed crystals, quasicrystals, phonon spectroscopy, Kapitza resistance, and quantum evaporation also contain material appearing in book form for the first time. The book is complemented by numerous diagrams that aid understanding and is comprehensively referenced for further study. With its unprecedented wide coverage of the field, The Physics of Phonons will be indispensable to all postgraduates, advanced undergraduates, and researchers working on condensed matter physics.

Book Description
This volume contains the proceedings of the Fourth International Conference on Phonon Scattering in Condensed Matter held from August 22-26, 1983 at the University of Stuttgart. The preceding conferences were organized at Saint Maxime and Paris in 1972, at the University of Nottingham in 1975, and at the Brown University Providence/Rhode Island in 1979. The Stuttgart conference, like the preceding conferences, was mainly con cerned with "propagating" high-frequency acoustic phonons, mechanical waves and heat up to the lattice limiting frequency. Lattice dynamics, optical pho nons, phase transitions, etc., were included as far as they are involved in acoustical phonon scattering, propagation and generation. In this context the conference covered all aspects of acoustical phonon physics, especially generation of phonons, propagation, scattering and detection. Since acoustic phonons participate in most energy-transfer processes in solids and liquids, the field of interest is growing rapidly. Therefore exciting new developments of acoustic phonon physics could be presented at the Stuttgart conference as well as important progress with respect to well-known problems, as, for example, the Kapitza resistance. Two hundred and six scientists from 21 countries attended the conference. Thirteen invited papers and 105 contributed papers, with 34 as posters, were presented. The discussions are included in this volume. A discussion session on large wave vector phonons was organized and chaired by V. Narayanamurti. A discussion session on phonon scattering at interfaces was organized and chaired by R.O. Pohl.
