Progress in Low Temperature Physics

Vol. 6 includes contents of v. 1-5.

As the growing number of conference proceedings, preprints, periodicals and popular journal articles are being joined by various electronic forms of dissemination of research, the series Progress in Low Temperature Physics assumes a particular responsibility in providing excellent reviews, guiding the reading of the literature and providing direction for future research possibilities. In this most recent volume, the main theme is research on superfluid and adsorbed phases of helium. In five chapters the following topics are dealt with. Chapter one is a review of one of the essential characteristics of superfluid 4He, the Landau critical velocity. Chapter two reviews the amazing properties of coherent spin dynamics in superfluid 3He. The next chapter examines a unique situation with a number of thermodynamic transitions between superfluid states and discusses the current experimental and theoretical situation. Properties of phases of 3He adsorbed on graphite are discussed in the following chapter, and in a complementary final chapter a review is presented on the properties of multilayer 3He-4He mixture films.

High pressure science is a rapidly growing diverse fi. e1d. The high pressure technique has become a powerful tool for both the study and preparation of materials. In spi. te of the many high pressure conferences held in recent years, I felt that there was a need for scientists within a well-defined area (not bound merely by the common experimental technique) to meet in an atmosphere conducive to frank exchange and close interaction. In this spirit, the Cleveland State University hosted such a conference from July 20 to 22, 1977, in which the physics of solids under high pressures and at low tempera tures was specifically examined. Both the original and review papers presented at the conference and the candid discussions following their presentations appear in this volume. They clearly cover a rather complete spectrum of current research in the physics of solids at high pressures and low temperatures. I wish to thank the National Aeronautics and Space Administra tion, the Office of Naval Research and the National Science Founda tion for their financial support of the conference. In addition, I wish especially to thank Steinar Huang for his unceasing assistance in arranging this conference. I also wish to thank him and Francis Stephenson for their assistance in preparing this book. C. W.

Market: Graduate students in condensed matter and atomic and molecular physics. This engagingly written book introduces the field and provides important information for those making low temperature measurements. Fundamental thermodynamic considerations are covered at the start and the book concludes with commercial applications and an appendix on laser cooling.

This book is primarily about the methodological questions involved in attempts to understand two of the most peculiar phenomena in physics, both occurring at the lowest of temperatures. Superconductivity (the disappearance of electrical resistance) and superfluidity (the total absence of viscosity in liquid helium) are not merely peculiar in their own right. Being the only macroscopic quantum phenomena they also manifest a sudden and dramatic change even in those properties which have been amply used within the classical framework and which were thought to be fully understood after the advent of quantum theory. A few years ago we set ourselves the task of carrying out a methodological study of the "most peculiar" phenomena in physics and trying to understand the process by which an observed (rather than predicted) new phenomenon gets "translated" into a physical problem. We thought the best way of deciding which phenomena to choose was to rely on our intuitive notion about the "degrees of peculiarity" developed, no doubt, during the past ten years of active research in theoretical atomic and elementary particle physics. While the merits of the different candidates were compared, we were amazed to realize that neither the phenomena of the very small nor those of the very large could compete with the phenomena of the very cold. These were truly remarkable phenomena if for no other reason than for the difficulties encountered in merely describing them.

This book contains a full exposition of the Bardeen-Cooper-Schrieffer (BCS) theory and its experimental verification, the Ginzburg-Landau theory, and the Gor'kov treatment of superconductivity. It discusses the fundamental experiments on macroscopic quantum phenomena and the Josephson effect.
