Book Description
Helium 4 is a collection of materials that examines the various properties of helium 4. The book presents 12 experimental studies and seven theoretical studies. The coverage of the text includes the viscosity of liquid helium below the ?-point; the transfer of helium II on glass; and the determination of the velocity of propagation of the second sound in helium II. The theoretical papers tackle topics such as the theory of superfluidity of helium II; radiation of sound in helium II; and the kinetic coefficients of helium II. The book will be of great interest to chemists, chemical engineers, and other scientists from related fields.

Book Description
Collected Papers of L. D. Landau brings together the collected papers of L. D. Landau in the field of physics. The discussion is divided into the following sections: low-temperature physics (including superconductivity); solid-state physics; plasma physics; hydrodynamics; astrophysics; nuclear physics and cosmic rays; quantum mechanics; quantum field theory; and miscellaneous works. Topics covered include the intermediate state of supraconductors; the absorption of sound in solids; the properties of metals at very low temperatures; and production of showers by heavy particles. This volume is comprised of 100 chapters and begins with Landau's paper on the theory of the spectra of diatomic molecules, followed by his studies on the damping problem in wave mechanics; quantum electrodynamics in configuration space; electron motion in crystal lattices; and the internal temperature of stars. Some of Landau's theories, such as those of stars, energy transfer on collisions, phase transitions, and specific heat anomalies are discussed. Subsequent chapters focus on the structure of the undisplaced scattering line; the transport equation in the case of Coulomb interactions; scattering of light by light; and the origin of stellar energy. This book will be a valuable resource for physicists as well as physics students and researchers.

Book Description
This book covers main properties of the excitation spectrum in superfluid 4He and the thermodynamics determined by the spectrum. It deals with hydrodynamics and describes that quantitative results should be insignificantly modified with processes of phonon decay taken into account.

Book Description
Quantum Liquids contains lectures presented at the International School of Low Temperature Physics in Erice, Italy, on June 11-25, 1977. The book reviews developments in the study of superfluid phases of the 3He system and in the understanding of quasiparticles and their interactions in the Bose 4He system, along with recent work on the 3He-4He mixtures. Comprised of 10 chapters, this volume begins with an overview of the renormalization group theory, critical phenomena, and phase transition in superfluid helium. It then discusses the superfluid density and the nature of critical singularities, the theory and practice of neutron scattering, and scattering from weakly interacting quantum liquids. The reader is also introduced to the superfluidity of liquid helium films, light scattering from superfluid helium, and the theory of superfluid 3He. Other chapters focus on superfluid flow in helium-4 compared to that in helium-3, the physical properties of small droplets of helium as analogs of heavy nuclei, and experimental properties of superfluid 3He. Excitations in 3He-4He mixtures, bound excitations in liquid He4, and temperature dependence of the single roton energy and lifetime are also discussed. Physicists and students of physics will find this book extremely useful.

Book Description
Originally published as two separate volumes, The Theory of Quantum Liquids is a classic text that attempts to describe the qualitative and unifying aspects of an extremely broad and diversified field. Volume I deals with ‘normal’ Fremi liquids, such as 3He and electrons in metals. Volume II consists of a detailed treatment of Bose condensation and liquid 4He, including the development of a Bose liquid theory and a microscopic basis for the two-fluid model, and the description of the elementary excitations of liquid HeII.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 26 (thesis year 1981) a total of 11 ,048 theses titles from 24 Canadian and 21 8 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 26 reports theses submitted in 1981, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
