Tunneling Systems in Amorphous and Crystalline Solids

The aim of this book is to provide a wealth of information on the influence of quantum-tunneling systems on the low-temperature properties of solids. The nineteen contributors of this book review thermodynamic, acoustic, dielectric and optical properties of amorphous and crystalline solids in eight chapters. The newest experiments on long-time spectral diffusion and heat release, electric field and strain effects, as well as nonequilibrium phenomena are thoroughly discussed. Several theoret...
