Download or read book Introduction to Unconventional Superconductivity written by V.P. Mineev and published by CRC Press. This book was released on 1999-09-21 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unconventional superconductivity (or superconductivity with a nontrivial Cooper pairing) is believed to exist in many heavy-fermion materials as well as in high temperature superconductors, and is a subject of great theoretical and experimental interest. The remarkable progress achieved in this field has not been reflected in published monographs and textbooks, and there is a gap between current research and the standard education of solid state physicists in the theory of superconductivity. This book is intended to meet this information need and includes the authors' original results.

Download or read book Strong Fermion Interactions in Fractional Quantum Hall States written by Shashikant Mulay and published by Springer. This book was released on 2018-10-26 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents an intuitive theory of trial wave functions for strongly interacting fermions in fractional quantum Hall states. The correlation functions for the proposed fermion interactions follow a novel algebraic approach that harnesses the classical theory of invariants and semi-invariants of binary forms. This approach can be viewed as a fitting and far-reaching generalization of Laughlin’s approach to trial wave functions. Aesthetically viewed, it illustrates an attractive symbiosis between the theory of invariants and the theory of correlations. Early research into numerical diagonalization computations for small numbers of electrons shows strong agreement with the constructed trial wave functions.The monograph offers researchers and students of condensed matter physics an accessible discussion of this interesting area of research.

Download or read book Pair Correlations in Many Fermion Systems written by Vladimir Z. Kresin and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: At first glance, the articles in this book may appear to have nothing in common. They cover such seemingly disparate subjects as the properties of small metallic clusters and the behavior of superfluid He3, nuclear physics and organic materials, copper oxides and mag netic resonance. Why have they been brought together, particUlarly in our time of narrow spe cialization? In fact, the properties and effects described in this book touch upon one and the same fundamental phenomenon: pair correlation. Introduced in the theory of superconductivity by J. Bardeen, L. Cooper, and J. Schrieffer (BCS), this effect plays a key role in various Fermi systems. The book consists of several sections. The first chapter is concerned with conven tional and high Tc superconductors. The second chapter describes two relatively young fami lies of superconductors: organics and fullerenes. Chapter III addresses the superfluidity of 3 He • The discovery of this phenomenon in 1971 was a big event in physics and last year was acknowledged by a Nobel prize. This book contains the text of the Nobel lecture. Chapters IV and V are devoted to correlations in finite Fermi systems such as small metallic clusters, C 60 anions, and atomic nuclei. The book thus covers a broad range of problems, illuminating the close ties between various areas of physics.

Available in PDF, EPUB and Kindle. Book excerpt: Particle-hole condensates in the angular momentum l=2 channel, known as d-density wave orders, have been suggested to be realized in strongly correlated electron systems. In this dissertation, we study singlet and triplet $d$-density wave orders with a form factor of d_(x2-y2) as well as a novel topological mixed singlet-triplet d-density wave with a form factor of (i[sigma] d_(x2-y2)+d_(xy)), and discuss the connections of these states to high-temperature superconductors and heavy-fermion materials. In Chapter 2, we discuss the spin susceptibility of the singlet d-density wave, triplet d-density wave, and spin density wave orders with hopping anisotropies. From the numerical calculation, we find nearly vertical dispersion relations for spin excitations with anisotropic incommensurability at low energies in agreement with the inelastic neutron scattering experiments in the pseudogap state of the high-temperature superconductor YBa2Cu3O6.6. The vertical dispersion is a distinct feature of all three density wave states in contrast to the superconducting state, which shows an hourglass shape dispersion experimentally. In Chapter 3, we explore a mixed singlet-triplet d-density wave state in a two-dimensional square lattice, which is topologically nontrivial and exhibits quantum spin Hall effect. We also study the bulk-edge correspondence and Lifshitz transition in the system. In Chapter 4, we show that the skyrmions in the system carry charge 2e and can condense into a superconducting state. The phase transition between the density wave and superconductivity likely leads to deconfined quantum critical points. We suggest connections of this exotic state to the hidden-order state in the heavy-fermion compound URu2Si2. The st-DDW model is generalized to three dimensions in Chapter 5, where we propose a novel pairing mechanism in URu2Si2. We assume the charge 2e skyrmionic spin texture in the mixed singlet-triplet d-density wave state fractionalizes into merons and antimerons at the deconfined quantum critical point. The interaction between these fractional particles results in a spin-singlet chiral d-wave superconducting state consistent with experiments. The unconventional superconductivity breaks time reversal symmetry, so we expect a polar Kerr effect at the onset of the superconductivity, but not in the time-reversal-invariant hidden-order state except perhaps for magnetic impurities.

Download or read book Frontiers of 4D and 5D transition Metal Oxides written by Gang Cao and published by World Scientific. This book was released on 2013 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is aimed at advanced undergraduates, graduate students and other researchers who possess an introductory background in materials physics and/or chemistry, and an interest in the physical and chemical properties of novel materials, especially transition metal oxides.New materials often exhibit novel phenomena of great fundamental and technological importance. Contributing authors review the structural, physical and chemical properties of notable 4d- and 5d-transition metal oxides discovered over the last 10 years. These materials exhibit extraordinary physical properties that differ significantly from those of the heavily studied 3d-transition metal oxides, mainly due to the relatively strong influence of the spin-orbit interaction and orbital order in 4d- and 5d materials. The immense growth in publications addressing the physical properties of these novel materials underlines the need to document recent advances and the current state of this field. This book includes overviews of the current experimental situation concerning these materials.

Download or read book Probing The Nuclear Paradigm With Heavy Ion Reactions Proceedings Of The International School Of Heavy Ion Physics written by Ricardo Americo Broglia and published by World Scientific. This book was released on 1995-02-22 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Major developments have taken place during the last few years in the study of the nuclear paradigm as a result of recent detector and accelerator developments, and of improved theoretical models.The active use of 4-π detectors to measure the gamma decay of excited nuclei has been instrumental in exploring the consequences of extremely high rotational frequencies and excitation energies in the nuclear structure. The identification of superdeformed bands, of limiting temperature for the detection of giant resonances, and of rotational damping, are conspicuous examples of this novel type of research. Studies of the disassembling of the nucleus have been systematically carried out, and the results interpreted in terms of transport models.At even higher temperatures one expects to have a completely new regime of hot dense matter, where the hadronic properties become strongly renormalized by the medium.Furthermore, studies of the properties of the nucleon as a many-body system of quarks and gluons displaying collective degrees of freedom which are damped by couplings to more complicated states, are providing a detailed and consistent picture of the nuclear paradigm.Important progress is also taking place in situations essentially opposite to the scenarios described above, namely in the study of correlations in nuclear matter at very low temperature and density.

Available in PDF, EPUB and Kindle. Book excerpt: The book includes 17 chapters written by noted scientists and young researchers and dealing with various aspects of superconductivity, both theoretical and experimental. The authors tried to demonstrate their original vision and give an insight into the examined problems. A balance between theory and experiment was preserved at least from the formal viewpoint (9 and 8, respectively). The readers should be warned that many of the problems studied here are far from being solved and are treated on the basis of competing viewpoints. The reason is that such is the state of the art! Science of superconductivity develops rapidly and new unexpected discoveries are expected in the nearest future.
