Liquid 4He and 3He are the purest Bose and Fermi liquids currently found in nature. Understanding their dynamics is fundamental to understanding more complex matter. This book provides an introduction to the subject and develops the theory of zero sound, phonons, rotons, spin and single particle excitations in quantum solids and fluids. Similarities between quantum solids and fluids are drawn wherever possible. Topics include dynamic response functions, neutron studies of solid helium, the nature of excitations in 3He, approximations to the dynamic susceptibility, and intermediate and high momentum transfer, among many others. In offering a critical comparison between theory and up-to-the-minute experimental data, the book provides a comprehensive assessment of our current understanding of collective and single particle excitations in quantum liquids and solids.
`a fine addition to the literature. It belongs on the bookshelf of anyone seriously interested in understanding the theory of excitations in quantum fluids and solids. ... This is a fine book. I highly recommend it to those who are entering the field, those who want a tutorial on the subjects covered and those who want a guide to the relevant literature.'
