Perspectives on Superconductivity Research by Paul S. Lewis Pdf

Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense, world-wide, research effort during this time, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such "strongly correlated" solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. High-Tc superconductors also have significant potential for applications in technologies ranging from electric power generation and transmission to digital electronics. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminium wires of the same size. Many universities, research institutes and companies are working to develop high-Tc superconductivity applications and considerable progress has been made. This new volume brings together new leading-edge research in the field.

Superconductivity by Paulette Grant Pdf

This book presents research on superconductivity. The first chapter discusses the physical properties of two nonmagnetic noncentrosymmetric superconductors, LaRhSi3 and LaIrSi3. Chapter two reviews the SrFe2As2 and FeTe0.8S0.2 compounds, which are perspective for developing new superconducting materials on their basis. The possibility of selective excitation of the nonlinear lattice vibrations in high-temperature superconductors formed from layers or thin films opens the new perspectives in the manipulations and control of quantum field in superconducting phase, which is further discussed in chapter three. Chapter four begins with a detailed derivation of the three coupled integral equations associated with the so-called generalised Bose-Einstein condensation formalism of a many-fermion system. Finally, chapter five proposes a microscopic theory of superconductivity based on the spinfluctuation mechanism of pairing.

High-Tc Superconductivity by Nie Luo,George H. Miley Pdf

The exciton mechanism of high-Tc superconductivity in copper oxides was initially proposed by Prof. J. Bardeen. His insight is largely shared by another luminary in superconductivity, Prof. V. L. Ginzburg. The main author of the book, Dr. Nie Luo, was motivated by their insights to give a geometrical explanation to the excitonic Coulomb interaction and has developed a unique formalism to understand and predict physical properties of high-Tc superconductors. This work is supported by increasingly strong evidence for electron–hole interactions in p-type cuprates. The presence of electrons in hole-doped cuprates is revealed by the works of the authors and many others, including the late Prof. L. P. Gor’kov. The book also tries to understand the interlayer Coulomb (ILC) pairing model by the excitonic Coulomb interaction. Developed by Prof. A. J. Leggett, ILC theory shares many views with Ginzburg’s approach. The other author of the book, Prof. George H. Miley, shares with us his personal experience with Prof. Bardeen on the exciton’s role in physics problems including high-Tc superconductivity. The results and predictions of this excitonic Coulomb mechanism have been verified by an increasing number of experiments. This book summarizes the current status and fathoms future directions.

Superconductivity Research Developments by James R. Tobin Pdf

Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect). The electrical resistivity of a metallic conductor decreases gradually as the temperature is lowered. However, in ordinary conductors such as copper and silver, impurities and other defects impose a lower limit. Even near absolute zero a real sample of copper shows a non-zero resistance. The resistance of a superconductor, on the other hand, drops abruptly to zero when the material is cooled below its "critical temperature", typically 20 kelvin or less. An electrical current flowing in a loop of superconducting wire can persist indefinitely with no power source. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It cannot be understood simply as the idealisation of "perfect conductivity" in classical physics. Superconductivity occurs in a wide variety of materials, including simple elements like tin and aluminium, various metallic alloys and some heavily-doped semiconductors. Superconductivity does not occur in noble metals like gold and silver, nor in most ferromagnetic metals. In 1986 the discovery of a family of cuprate-perovskite ceramic materials known as high-temperature superconductors, with critical temperatures in excess of 90 kelvin, spurred renewed interest and research in superconductivity for several reasons. As a topic of pure research, these materials represented a new phenomenon not explained by the current theory. And, because the superconducting state persists up to more manageable temperatures, more commercial applications are feasible, especially if materials with even higher critical temperatures could be discovered. This new book presents leading research from around the world in this dynamic field.
