Book Description
This book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8 by vacuum, ultra-violet, laser-based, angle-resolved photoemission spectroscopy (ARPES). A new form of electron coupling has been identified in Bi2212, which occurs in the superconducting state. For the first time, the Bogoliubov quasiparticle dispersion with a clear band back-bending has been observed with two peaks in the momentum distribution curve in the superconducting state at a low temperature. Readers will find useful information about the technique of angle-resolved photoemission and the study of high-temperature superconductors using this technique. Dr. Wentao Zhang received his PhD from the Institute of Physics at the Chinese Academy of Sciences.

Book Description
There are many theories at present which attempt to explain the property of high-temperature superconductivity in the new breed of superconducting ceramics - however, the electronic structure of these materials is not yet fully understood. The 29 papers in this work present the results from the use of a wide range of spectroscopic techniques, such as Raman, nuclear magnetic resonance and photoemission, in investigating the electronic structure of the new cuprate perovskites.

Book Description
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.

Book Description
This Workshop addresses the role of magnetic interactions in the various aspects of high Tc superconducting materials, including the fundamental nature of the elementary excitations and their effect on the measured microscopic and macroscopic magnetic properties of these materials. Applications involving the magnetic behaviour of high Tc superconductors is a special feature of this Workshop.

Book Description
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.

Book Description
Angle-resolved photoemission has become an indispensable tool for solid state and surface physicists and chemists. This book covers the underlying phenomenology of the technique, reviews its application to existing problems, and discusses future applications. The book is particularly timely given the significant improvements in experimental and theoretical methodology which have recently been or soon will be attained, namely, ultrahigh resolution studies using improved sources of synchrotron radiation, quasiparticle interpretation of measured dispersion relations and spectra, in situ growth of novel materials, etc. The technique has been applied predominantly to understand materials for which the one-electron paradigm is a reasonable approximation. Most chapters discuss this type of experiment: 2D and 3D states in metals and semiconductors, extrinsic states induced by adsorption, etc. Applications of the technique to materials where electron correlation plays a comparable role to that of solid state hybridization, ferro- and antiferromagnets, high Tc superconductors, etc. are rapidly growing in popularity. These areas are also discussed and a foundation is laid for further experiments in this direction. Almost all chapters contain comprehensive bibliographies and compendia of systems studied. The book has an extensive index which cross references applications and systems studied.
