Available in PDF, EPUB and Kindle. Book excerpt: It is now ten years since it was first convincingly shown that below 1 K the ther mal conductivity and the heat capacity of amorphous solids behave in a way which is strikingly different to that of crystalline solids. Since that time there has been a wide variety of experimental and theoretical studies which have not only defined and clarified the low temperature problem more closely, but have also linked these differences between amorphous and crystalline solids to those suggested by older acoustic and thermal experiments (extending up to 100 K). The interest in this somewhat restricted branch of physics lies to a considerable extent in the fact that the differences were so unexpected. It might be thought that as the tempera ture, probing frequency, or more generally the energy decreases, a continuum de scription in which structural differences between glass and crystal are concealed should become more accurate. In a sense this is true, but it appears that there exists in an amorphous solid a large density of additional excitations which have no counterpart in normal crystals. This book presents a survey of the wide range of experimental investigations of these low energy excitations, together with a re view of the various theoretical models put forward to explain their existence and nature.
Download or read book Thermal Properties of Solids at Room and Cryogenic Temperatures written by Guglielmo Ventura and published by Springer. This book was released on 2014-06-23 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The minimum temperature in the natural universe is 2.7 K. Laboratory refrigerators can reach temperatures in the microkelvin range. Modern industrial refrigerators cool foods at 200 K, whereas space mission payloads must be capable of working at temperatures as low as 20 K. Superconducting magnets used for NMR work at 4.2 K. Hence the properties of materials must be accurately known also at cryogenic temperatures. This book provides a guide for engineers, physicists, chemists, technicians who wish to approach the field of low-temperature material properties. The focus is on the thermal properties and a large spectrum of experimental cases is reported. The book presents updated tables of low-temperature data on materials and a thorough bibliography supplements any further research. Key Features include: ° Detailed technical description of experiments ° Description of the newest cryogenic apparatus ° Offers data on cryogenic properties of the latest new materials ° Current reference review

Download or read book Cryogenics and Measurement of Properties of Solids at Low Temperatures written by R. Srinivasan and published by Allied Publishers. This book was released on 2008-04-05 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperature research has become fairly widespread in the country after the availability of closed cycle refrigerators. It is opportune to write a book for students and researchers in India on production of low temperatures and techniques for the measurement of physical properties of materials at such temperatures. This book is an effort in this direction. The first part of the book discusses methods for producing temperatures down to 1.8 K. There is a fairly extensive discussion on different types of closed cycle refrigerators. The behaviour of properties of materials relevant in Cryogenics is dealt with in some detail. Useful tips on construction of cryostats are given. Thermometry is discussed extensively. The second part of the book deals with digital measuring techniques. Details of experimental methods for measuring thermal and electrical properties, point contact tunneling, scanning probe microscopy, and noise at low temperatures are discussed. This part of the book is born out of the rich personal experience in such measurements of one of the authors (AKR). There is an appendix on vacuum techniques. The book can be used for teaching an elective course in Low Temperature Physics at the M.Sc. level. It will be useful for researchers in Low Temperature Physics.
Download or read book Low Temperature Properties of Polymers written by I. Perepechko and published by Elsevier. This book was released on 2013-10-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-Temperature Properties of Polymers systematizes the available materials on polymers. This book also describes the main trends in the investigation of interrelated properties of polymers, such as thermal (heat capacity, thermal conductivity, and thermal expansion), acoustical, dielectric, and viscoelastic, which maintain the physical properties of polymers at low temperatures. Comprised of nine chapters, this book first covers heat capacity of polymers at low temperature, and then tackles thermal conductivity of polymers at low temperatures. Chapter 3 discusses thermal expansion of polymers at low temperatures, and Chapter 4 tackles electrical properties of polymers at low temperatures. The fifth chapter covers nuclear magnetic resonance in polymers at low temperature, while the succeeding chapter encompasses dynamic mechanical properties of polymers at low temperatures. Chapter 7 concerns itself with the acoustical properties of polymers at low temperatures, while the succeeding chapter covers viscoelastic parameters of polymers at low temperatures. The closing chapter covers how to determine the thermophysical characteristics of polymers by acoustic measurement at helium temperature. This book will be of great interest to researchers or professionals whose line of work involves the manipulation and understanding of the properties of polymers.
Download or read book Low temperature Thermal And Vibrational Properties Of Disordered Solids A Half century Of Universal Anomalies Of Glasses written by Miguel A Ramos and published by World Scientific. This book was released on 2022-08-11 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, edited by M. A. Ramos and contributed by several reputed physicists in the field, presents a timely review on low-temperature thermal and vibrational properties of glasses, and of disordered solids in general. In 1971, the seminal work of Zeller and Pohl was published, which triggered this relevant research field in condensed matter physics. Hence, this book also commemorates about 50 years of that highlight with a comprehensive, updated review.In brief, glasses (firstly genuine amorphous solids but later on followed by different disordered crystals) were found to universally exhibit low-temperature properties (specific heat, thermal conductivity, acoustic and dielectric attenuation, etc.) unexpectedly very similar among them — and very different from those of their crystalline counterparts.These universal 'anomalies' of glasses and other disordered solids remain very controversial topics in condensed matter physics. They have been addressed exhaustively in this book, through many updated experimental data, a survey of most relevant models and theories, as well as by computational simulations.

Download or read book Matter and Methods at Low Temperatures written by Frank Pobell and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide information about performing experi ments at low temperatures, as well as basic facts concerning the low tem perature properties of liquid and solid matter. To orient the reader, I begin with chapters on these low temperature properties. The major part of the book is then devoted to refrigeration techniques and to the physics on which they are based. Of equal importance, of course, are the definition and measurement of temperature; hence low temperature thermometry is extensively discussed in subsequent chapters. Finally, I describe a variety of design and construction techniques which have turned out to be useful over the years. The content of the book is based on the three-hour-per-week lecture course which I have given several times at the University of Bayreuth between 1983 and 1991. It should be particularly suited for advanced stu dents whose intended masters (diploma) or Ph.D. subject is experimental condensed matter physics at low temperatures. However, I believe that the book will also be of value to experienced scientists, since it describes sev eral very recent advances in experimental low temperature physics and technology, for example, new developments in nuclear refrigeration and thermometry.
