This book was released on 2019-05-02 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within this work, the pairing mechanism of conventional (Pb) and unconventional superconductors (SrFe2(As1-xPx )2 , FeSe, FeSe/STO) was investigated experimentally by means of elastic and inelastic tunneling spectroscopy at temperatures down to 30 mK. The distinction between elastic and inelastic contributions to tunneling data was elaborated. The results help to identify conventional (phonon-mediated) and unconventional (e.g. spin-?uctuation mediated) superconductivity.

Download or read book Andreev Reflection in Superconducting Junctions written by Yasuhiro Asano and published by Springer Nature. This book was released on 2021-11-12 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a primer on the fundamental theory of Andreev reflection, a fundamental process in the motion of a Cooper pair, which dominates low-energy electronic transport properties in superconductor junctions including differential conductance and Josephson current. The book concisely describes how Andreev reflection impacts the low-energy physics of electronic transport especially in topologically non-trivial superconductor junctions. In addition, it includes an introduction to topological superconductors, covering topological classification, chiral and helical superconductors, and topological edges. The book is based on the author’s lecture notes, used in his intensive lectures and while supervising his upper undergraduate and early graduate students. To fully benefit from this concise primer, readers only need an undergraduate background in quantum mechanics and statistical mechanics. Further, by highlighting Josephson junctions of topological superconductors, the book offers readers a glimpse into cutting-edge topics.

A critical discussion of theoretical proposals is presented under the constraints of experimental observations and exciting possibilities for the symmetry of the order parameter are presented, including the cases of inhomogeneous superconducting states and triplet superconductivity. The possible origins of Cooper pairing are explored and tests to detect experimentally the pairing symmetry are described in detail. The book ends with a discussion of important open questions, where the search for their answers will keep the field alive for the next decade.
Download or read book Fullerenes And Fullerene Nanostructures Proceedings Of The International Winter School On Electronic Properties Of Novel Materials written by Jorg Fink and published by World Scientific. This book was released on 1996-08-30 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last ten years, the International Winterschools on Electronic Properties of New Materials (IWEPNM) have developed into a well-established institution and the alumni form a very active interdisciplinary community which spreads all over the world. Past schools of this series have treated such topics as conducting polymers and high temperature superconductors. The present volume contains the proceedings of the fourth school on fullerenes and fullerene derivatives. Soccer-ball molecules, like C₆₀, C₇₀, etc., have been discovered in the late 1980's and are now regarded as the third allotrope of carbon (in addition to the classic allotropes graphite and diamond). By now, more than ten thousand original papers on fullerene have been published, and the present proceedings give a snap-shot of the development of the field and the state of the art, as reflected by research papers, overviews, and tutorial lectures. Highlights are contributions on fullerene polymers, magnetic properties of fullerene complexes, endohedral compounds, fullerenes with incorporated heteroatoms, and on fullerene nanotubes (single-walled, multi-walled, with open cores or metal-filled), as well as prospects of technological applications (field emission electron guns for flat video displays, fullerene plasma for vapour deposited diamond and SiC film, etc.).

Download or read book The Gap Symmetry and Fluctuations in High Tc Superconductors written by Julien Bok and published by Springer Science & Business Media. This book was released on 2006-03-07 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery in 1986 of high temperature superconductors by J. G. Bednorz and K. A. Müller, a considerable progress has been made and several important scientific problems have emerged. Within this NATO Advanced Study Institute our intention was to focus mainly on the controversial topic of the symmetry of the superconducting gap and given the very short coherence length, the role of fluctuations. The Institute on ‘The Gap Symmetry and Fluctuations in High- Superconductors’ took place in the “Institut d’Etudes Scientifiques de Cargèse” in Corsica, France, between 1 - 13 September 1997. The 110 participantsfrom 18 countries (yet 30 nationalities) including 23 full time lecturers, have spent two memorable weeks in this charming Mediterranean resort. All lecturers were asked to prepare pedagogical papers to clearly present the central physical idea behind specific model or experiment. The better understanding of physics of high temperature superconductivity is certainly needed to guide the development of applications of these materials in high and weak current devices.

Download or read book Physics and Materials Science of High Temperature Superconductors IV written by R. Kossowsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five questions dominated the ARW on Physics and Materials Science of High Temperature Superconductors, of which this book forms the permanent record. Briefly, these are: (i) How close are we to a unified theory? The consensus is that we are not. (ii) Flux pinning: can it be achieved in bulk materials? Still an open question. The following three questions are related. (iii) Can grain boundary contributions be brought under control? (iv) What is the real requirement for purity and general chemistry control? (v)What is the practical outlook for bulk products - tapes and wires? One of the conclusions is that the geometry and dimensions in thin films are the key parameters that facilitate the realization of high current densities and, consequently, their commercial application. On the other hand, the very large number of poorly understood microstructural, chemical and mechanical variables involved in the preparation of bulk materials are currently prohibiting large scale commercialization of wires and tapes.

At the 12th Symposium, a mini-symposium focusing on the two-dimensionality of high-temperature superconductors, or the c-axis transport, and a session on vortex physics were organized. There were also many reports on the recent developments of YBCO-based coated conductors both in the United States and in Japan, AC losses of wires and tapes, developments of bulk materials with strong flux pinning, the recent progress in thin film and junction technologies, and the demonstration of various electronics applications using SQUIDs, microwave devices, and single-flux-quantum (SFQ) digital devices. This volume is a valuable resource for all those working in the field of superconductivity.
