Physical Acoustics: Principles and Methods, Volume IV, Part B: Applications to Quantum and Solid State Physics provides an introduction to the various applications of quantum mechanics to acoustics by describing several processes for which such considerations are essential. This book discusses the transmission of sound waves in molten metals. Comprised of seven chapters, this volume starts with an overview of the interactions that can happen between electrons and acoustic waves when magnetic fields are present. This text then describes acoustic and plasma waves in ionized gases wherein oscillations are subject to hydrodynamic as well as electromagnetic forces. Other chapters examine the resonances and relaxations that can take place in polymer systems. This book discusses as well the general theory of the interaction of a weak sinusoidal field with matter. The final chapter describes the sound velocities in the rocks composing the Earth. This book is a valuable resource for physicists and engineers.

Physical Acoustics: Principles and Methods reviews the principles and methods of physical acoustics and covers topics ranging from relaxation processes in sound propagation in fluids to acoustic vibrational modes in quartz crystals, along with electron and phonon drag on mobile dislocations in metals at low temperatures. Two-pulse phonon echoes in solid-state acoustics and memory echoes in powders are also discussed. Comprised of seven chapters, this volume begins with a historical account of relaxation processes in sound propagation, followed by an analysis of acoustic vibrational modes in quartz crystals. The reader is then introduced to electron and phonon drag on mobile dislocations at low temperatures, together with two-pulse phonon echoes in solid-state acoustics and dynamic polarization echoes in powdered materials. The book also considers memory echoes in powders before concluding with an evaluation of acousto-optic transduction mechanisms used in fiber optic acoustic sensors, together with their practical implementation. This book will be of interest to physicists.

Physical Acoustics: Principles and Methods, Volume IV, Part A: Applications to Quantum and Solid State Physics provides an introduction for the various applications of quantum mechanics to acoustics by describing several processes for which such considerations are essential. This book explores the magnetic fields applied to metals in the normal state, which have the effect of localizing the interaction between the acoustic waves and the electrons to specific parts of the Fermi surface. Organized into nine chapters, this volume starts with an overview of the transmission of sound waves in semiconducting crystals that are piezoelectric. This text then examines the reactions of nonpiezoelectric semiconductors with electrons through the deformation potential that changes the shape of the Fermi surface. Other chapters consider the amplification of acoustic waves in semiconductors by the application of an electric field. The final chapter examines how measurements can delineate the Fermi surface of monovalent metals. Physicists and engineers will find this book useful.
