Available in PDF, EPUB and Kindle. Book excerpt: Holger Bartolf discusses state-of-the-art detection concepts based on superconducting nanotechnology as well as sophisticated analytical formulæ that model dissipative fluctuation-phenomena in superconducting nanowire single-photon detectors. Such knowledge is desirable for the development of advanced devices which are designed to possess an intrinsic robustness against vortex-fluctuations and it provides the perspective for honorable fundamental science in condensed matter physics. Especially the nanowire detector allows for ultra-low noise detection of signals with single-photon sensitivity and GHz repetition rates. Such devices have a huge potential for future technological impact and might enable unique applications (e.g. high rate interplanetary deep-space data links from Mars to Earth).
Download or read book Mechanisms of High Temperature Superconductivity written by Hiroshi Kamimura and published by Springer. This book was released on 2011-12-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery by Bednorz and Müller of Cu-O alloys displaying high temperature superconductivity, great energy has been put into research in this field. One of the most important and interesting issues, and the subject of this volume, is the clarification of the microscopic origin and mechanism of high temperature superconductivity. This book discusses the latest experimental results on magnetic, optical, electrical, thermal and mechanical properties of the Cu-O and Bi-O superconductors, as well as proposed theoretical models of the mechanisms. The participants in the symposium agreed that for the high Tc Cu-O superconductors electron correlation effects are of central importance. For the Bi-O superconductors the main topic was whether the mechanism of superconductivity is the same as that of high Tc Cu-O superconductors. What was and what was not resolved at the symposium is summarized at the end of the volume.
Download or read book Mechanisms of Conventional and High Tc Superconductivity written by Vladimir Z. Kresin and published by Oxford University Press. This book was released on 1993-06-17 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductivity has become one of the most intensely studied physical phenomena of our times, with tremendous potential to revolutionize fields as diverse as computing and transportation. This book describes the methods, established results, and recent advances in the field. The goal is to present recently developed theoretical models in light of the long-sought aim of achieving the effect at very high temperatures. The book includes a detailed review of various mechanisms, including phononic, magnetic, and electronic models. The authors focus on the phenomenon of induced superconductivity in the high-temperature oxides, particularly the high-transition-temperature cuprates. They also discuss a variety of low-temperature superconducting systems in conventional materials and organics. The book links the crucial experiments with the most current theories, offering a unified description of the phenomenon. All researchers (and graduate-level) students involved with work in superconductivity will find this an invaluable resource, including solid-state and condensed-matter physicists and chemists, and materials scientists.
Download or read book High Temperature Superconductivity in Cuprates written by A. Mourachkine and published by Springer Science & Business Media. This book was released on 2002-07-31 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of the book is to present a description of the mechanism of high-temperature superconductivity and to discuss the physics of high-temperature superconductors, both entirely based on experimental facts. The pairing mechanism of this remarkable phenomenon is based on an anomaly found in tunneling (V) characteristics of some cuprates. By using the soliton theory, it is then shown that this anomaly is caused by pairs of quasi-one dimensional excitations - bisolitons - bound due to a moderately strong, nonlinear electron-phonon interaction. At the same time, analysis of experimental data unambiguously shows that magnetic (spin) fluctuations mediate the phase coherence in cuprates. The mechanism of superconductivity in quasi-one dimensional organic superconductors and heavy fermions is discussed too. In cuprates, the origins of five different energy/temperature scales are identified. Finally, three main principles of superconductivity are introduced at the end of the book. Analysis of tunneling and angle-resolved photoemission measurements is presented in the last chapter. The book which contains 300 pages with 180 illustrations is addressed to researchers and graduate students in all branches of exact sciences.
Download or read book Statistical Mechanics of Superconductivity written by Takafumi Kita and published by Springer. This book was released on 2015-05-05 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a theoretical, step-by-step comprehensive explanation of superconductivity for undergraduate and graduate students who have completed elementary courses on thermodynamics and quantum mechanics. To this end, it adopts the unique approach of starting with the statistical mechanics of quantum ideal gases and successively adding and clarifying elements and techniques indispensible for understanding it. They include the spin-statistics theorem, second quantization, density matrices, the Bloch–De Dominicis theorem, the variational principle in statistical mechanics, attractive interaction and bound states. Ample examples of their usage are also provided in terms of topics from advanced statistical mechanics such as two-particle correlations of quantum ideal gases, derivation of the Hartree–Fock equations, and Landau’s Fermi-liquid theory, among others. With these preliminaries, the fundamental mean-field equations of superconductivity are derived with maximum mathematical clarity based on a coherent state in terms of the Cooper-pair creation operator, a quasiparticle field for describing the excitation and the variational principle in statistical mechanics. They have the advantage that the phase coherence due to the Cooper-pair condensation can be clearly seen making the superfluidity comprehensible naturally. Subsequently, they are applied to homogeneous cases to describe the BCS theory for classic s-wave superconductors and its extension to the p-wave superfluidity of 3He. Later, the mean-field equations are simplified to the Eilenberger and Ginzburg–Landau equations so as to describe inhomogeneous superconductivity such as Abrikosov’s flux-line lattice concisely and transparently. Chapters provide the latest studies on the quasiclassical theory of superconductivity and a discovery of p-wave superfluidity in liquid 3He. The book serves as a standard reference for advanced courses of statistical mechanics with exercises along with detailed answers.

Download or read book Novel Superconductivity written by Stuart A. Wolf and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1086 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Novel Mechanisms of Superconductivity Conference was initially conceived in the early part of 1986 as a small, 2-1/2 day workshop of 40-70 scientists, both theorists and experimentalists interested in exploring the possible evidence for exotic, non phononic superconductivity. Of course, the historic discoveries of high temperature oxide superconductors by Bednorz and Mftller and the subsequent enhancements by the Houston/Alabama groups made such a small conference impractical. The conference necessarily had to expand, 2-1/2 days became 4-1/2 days and superconductivity in the high Tc oxides became the largest single topic in the workshop. In fact, this conference became the first major conference on this topic and thus, these proceedings are also the first maj or publication. However, heavy fermion, organic and low carrier concentration superconductors remained a very important part of this workshop and articles by the leaders in these fields are included in these proceedings. Ultimately the workshop hosted rearly 400 scientists, students and media including representatives from the maj or research groups in the U.S., Europe, Japan and the Soviet Union.

Download or read book Superconductivity Begins With H Both Properly Understood And Misunderstood Superconductivity Basics Rethought written by Jorge E Hirsch and published by World Scientific. This book was released on 2020-06-16 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This iconoclastic book proposes that superconductivity is misunderstood in contemporary science and that this hampers scientific and technological development. Superconductivity is the ability of some metals to carry electric current without resistance at very low temperatures. Properly understanding superconductivity would facilitate finding materials that superconduct at room temperature, providing great benefits to society.The conventional BCS theory of superconductivity, developed in 1957 and awarded the Nobel Prize in 1972, is generally believed to fully explain the lower temperature 'conventional superconductors' but not the more recently discovered 'high temperature superconductors', for which the charge carriers are positive Holes rather than negative electrons. Instead, this book proposes the holistic view that Holes are responsible for superconductivity in all materials. It explains in simple terms how the most fundamental property of all superconductors, that they expel H-fields (the Meissner effect), can be understood with Hole carriers and cannot be explained by BCS. It describes the historical development of the conventional theory and why it went astray, and credits pre-BCS researchers for important insights that were forgotten after BCS but are in fact relevant for the proper understanding of superconductivity.The book's author, Jorge E Hirsch, is a renowned expert in the field of condensed matter physics who has published over 250 articles on the subject. He has developed the theory of 'Hole superconductivity', the focus of this book, over the last 30 years. He is also the inventor of the H-index, a bibliometric measure of scientific impact which, he admits in this book, fails to identify high scientific achievement in the field of superconductivity.
