High-Temperature Superconductivity in Cuprates

High-Temperature Superconductivity in Cuprates



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.

The Art of Writing Reasonable Organic Reaction Mechanisms

The Art of Writing Reasonable Organic Reaction Mechanisms



Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. The treatment emphasizes unifying principles, showing how common mechanisms link seemingly disparate reactions. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and ‘common error alerts’ are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.

The Attractor Mechanism

The Attractor Mechanism



This book is based upon lectures presented in June 2007 at the INFN-Laboratori Nazionali di Frascati School on Attractor Mechanism, directed by Stefano Bellucci. The symposium included such prestigious lecturers as S. Ferrara, M. Gnaydin, P. Levay, and T. Mohaupt. All lectures were given at a pedagogical, introductory level, which is reflected in the specific ‘flavor’ of this volume. The book also benefits from extensive discussions about, and related reworking of, the various contributions. In addition, this volume contains contributions originating from short presentations of recent original results and an essay on the relation between complexity science and high-energy physics by A. Zichichi. It is the fourth volume in a series of books on the general topics of supersymmetry, supergravity, black holes and the attractor mechanism.

Nonvolatile Memory Design

Nonvolatile Memory Design



The manufacture of flash memory, which is the dominant nonvolatile memory technology, is facing severe technical barriers. So much so, that some emerging technologies have been proposed as alternatives to flash memory in the nano-regime. Nonvolatile Memory Design: Magnetic, Resistive, and Phase Changing introduces three promising candidates: phase-change memory, magnetic random access memory, and resistive random access memory. The text illustrates the fundamental storage mechanism of these technologies and examines their differences from flash memory techniques. Based on the latest advances, the authors discuss key design methodologies as well as the various functions and capabilities of the three nonvolatile memory technologies.
