This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: By combining density functional theory and linear response theory, the normal mode frequencies of lattice vibration---phonons---are calculated from first-principles. Corresponding to the original Kohn-Sham equation with an external perturbation, the perturbed Kohn-Sham equation is solved self-consistently to give the variations in the density and the effective potential to linear order of the external perturbation. From these results, the dynamical matrices are calculated, and the phonon frequencies are obtained through direct diagonalization of the dynamical matrix.

Download or read book Electron–Lattice Interactions in Semiconductors written by Yuzo Shinozuka and published by CRC Press. This book was released on 2021-03-29 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents theoretical treatments on various electronic and atomic processes in non-metallic materials from a unified point of view. It starts with the basic properties of semiconductors, treating the system as a macroscopic association of electrons and ions. In their ground state, fruitful results are derived, such as the band theory for electrons in a periodic lattice and a useful concept of “hole.” The electron–lattice interaction is then introduced as a dynamical response of condensed matter when it is electronically excited. With the aid of proper configuration coordinate diagrams, various phenomena are precisely examined, including carrier scattering, polaron formation, lattice relaxation, Stokes shift and phonon side band in optical spectrum, intrinsic and extrinsic self-trapping, and structural changes. The book provides readers a deep understanding of the physics underlying these phenomena and excellent insight to develop their further research. Graduate students who have finished the basic study on solid-state physics and quantum mechanics and research scientists and engineers in materials science and engineering will benefit immensely from it.

Book excerpt: The goal of this Volume "Conceptual Foundations of Materials: A standard model for ground- and excited-state properties" is to present the fundamentals of electronic structure theory that are central to the understanding and prediction of materials phenomena and properties. The emphasis is on foundations and concepts. The Sections are designed to offer a broad and comprehensive perspective of the field. They cover the basic aspects of modern electronic structure approaches and highlight their applications to the structural (ground state, vibrational, dynamic and thermodynamic, etc.) and electronic (spectroscopic, dielectric, magnetic, transport, etc.) properties of real materials including solids, clusters, liquids, and nanostructure materials. This framework also forms a basis for studies of emergent properties arising from low-energy electron correlations and interactions such as the quantum Hall effects, superconductivity, and other cooperative phenomena. Although some of the basics and models for solids were developed in the early part of the last century by figures such as Bloch, Pauli, Fermi, and Slater, the field of electronic structure theory went through a phenomenal growth during the past two decades, leading to new concepts, understandings, and predictive capabilities for determining the ground- and excited-state properties of real, complex materials from first principles. For example, theory can now be used to predict the existence and properties of materials not previously realized in nature or in the laboratory. Computer experiments can be performed to examine the behavior of individual atoms in a particular process, to analyze the importance of different mechanisms, or just to see what happen if one varies the interactions and parameters in the simulation. Also, with ab initio calculations, one can determine from first principles important interaction parameters which are needed in model studies of complex processes or highly correlated systems. Each time a new material or a novel form of a material is discovered, electronic structure theory inevitably plays a fundamental role in unraveling its properties. - Provides the foundations of the field of condensed matter physics - An excellent supplementary text for classes on condensed matter physics/solid state physics - Volume covers current work at the forefront - Presentations are accessible to nonspecialists, with focus on underlying fundamentals

This book was released on 2006-06-08 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physicalkineticsisthe?nalsectionofthecourseoftheoreticalphysics in its standard presentation. It stays at the boundary between g- eral theories and their applications (solid state theory, theory of gases, plasma, and so on), because the treatment of kinetic phenomena always depends on speci?c structural features of materials. On the other hand, the physical kinetics as a part of the quantum theory of macroscopic systems is far from being complete. A number of its fundamental - sues, such as the problem of irreversibility and mechanisms of chaotic responses, are now attracting considerable attention. Other important sections, for example, kinetic phenomena in disordered and/or strongly non-equilibrium systems and, in particular, phase transitions in these systems, are currently under investigation. The quantum theory of m- surements and quantum information processing actively developing in the last decade are based on the quantum kinetic theory. Because a deductive theoretical exposition of the subject is not c- venient, the authors restrict themselves to a lecture-style presentation. Now the physical kinetics seems to be at the stage of development when, according to Newton, studying examples is more instructive than lea- ing rules. In view of these circumstances, the methods of the kinetic theory are presented here not in a general form but as applications for description of speci?c systems and treatment of particular kinetic p- nomena. The quantum features of kinetic phenomena can arise for several r- sons.

Available in PDF, EPUB and Kindle. Book excerpt: "Quantum Physics of the Solid State: an Introduction" Draft foreword: 26/09/03 If only this book had been available when I was starting out in science! It would have saved me countless hours of struggle in trying to apply the general ideas of the standard solid-state text-books to solve real problems. The fact is that most of the texts stop at the point where the real difficulties begin. The great merit of this book is that it describes in an honest and detailed way what one really has to do in order to understand the multifarious properties of solids in terms of the fundamental physical theory of quantum mechanics. University students of the physical sciences are taught about the fundamental the ories, and know that quantum mechanics, together with relativity, is our basis for understanding the physical world. But the practical difficulties of using quantum mechanics to do anything useful are usually not very well explained. The truth is that the application of quantum theory to achieve our present detailed understand ing of solids has required the development of a large array of mathematical tech niques. This is closely analogous to the challenge faced long ago by theoretical astronomers in trying to apply Newton's equations of motion to the heavens -they too had to develop a battery of theoretical and computational techniques to do cal culations that could be compared with observation.

Available in PDF, EPUB and Kindle. Book excerpt: "Solid-State Theory - An Introduction" is a textbook for graduate students of physics and material sciences. Whilst covering the traditional topics of older textbooks, it also takes up new developments in theoretical concepts and materials that are connected with such breakthroughs as the quantum-Hall effects, the high-Tc superconductors, and the low-dimensional systems realized in solids. Thus besides providing the fundamental concepts to describe the physics of the electrons and ions comprising the solid, including their interactions, the book casts a bridge to the experimental facts and gives the reader an excellent insight into current research fields. A compilation of problems makes the book especially valuable to both students and teachers.

Download or read book Fundamentals of Many-body Physics written by Wolfgang Nolting and published by Springer Science & Business Media. This book was released on 2009-03-02 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the present course on “Fundamentals of Theoretical Physics” is to be a direct accompaniment to the lower-division study of physics, and it aims at providing the ph- ical tools in the most straightforward and compact form as needed by the students in order to master theoretically more complex topics and problems in advanced studies and in research. The presentation is thus intentionally designed to be suf?ciently detailed and self-contained – sometimes, admittedly, at the cost of a certain elegance – to permit in- vidual study without reference to the secondary literature. This volume deals with the quantum theory of many-body systems. Building upon a basic knowledge of quantum mechanics and of statistical physics, modern techniques for the description of interacting many-particle systems are developed and applied to various real problems, mainly from the area of solid-state physics. A thorough revision should guarantee that the reader can access the relevant research literature without experiencing major problems in terms of the concepts and vocabulary, techniques and deductive methods found there. The world which surrounds us consists of very many particles interacting with one another, and their description requires in principle the solution of a corresponding number ofcoupledquantum-mechanicalequationsofmotion(Schrodinger ̈ equations),which,h- ever, is possible only in exceptional cases in a mathematically strict sense. The concepts of elementary quantum mechanics and quantum statistics are therefore not directly applicable in the form in which we have thus far encountered them. They require an extension and restructuring, which is termed “many-body theory”.

Download or read book Mössbauer Effect in Lattice Dynamics written by Yi-Long Chen and published by John Wiley & Sons. This book was released on 2007-09-24 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: This up-to-date review closes an important gap in the literature by providing a comprehensive description of the Mössbauer effect in lattice dynamics, along with a collection of applications in metals, alloys, amorphous solids, molecular crystals, thin films, and nanocrystals. It is the first to systematically compare Mössbauer spectroscopy using synchrotron radiation to conventional Mössbauer spectroscopy, discussing in detail its advantages and capabilities, backed by the latest theoretical developments and experimental examples. Intended as a self-contained volume that may be used as a complete reference or textbook, it adopts new pedagogical approaches with several non-traditional and refreshing theoretical expositions, while all quantitative relations are derived with the necessary details so as to be easily followed by the reader. Two entire chapters are devoted to the study of the dynamics of impurity atoms in solids, while a thorough description of the Mannheim model as a theoretical method is presented and its predictions compared to experimental results. Finally, an in-depth analysis of absorption of Mössbauer radiation is presented, based on recent research by one of the authors, resulting in an exact expression of fractional absorption, otherwise unavailable in the literature. The whole is supplemented by elaborate appendices containing constants and parameters.

This book was released on 1996-07-02 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant advances have been made towards understanding the properties of materials through theoretical approaches. These approaches are based either on first-principles quantum mechanical formulations or semi-empirical formulations, and have benefitted from increases in computational power. The advent of parallel computing has propelled the theoretical approaches to a new level of realism in modelling physical systems of interest. The theoretical methods and simulation techniques that are cur- rently under development are certain to become powerful tools in understanding, exploring and predicting the properties of existing and novel materials. This book discusses critically current developments in computations and simulational approaches specifically aimed at addressing real materials problems, with an emphasis on parallel computing and shows the most successful applications of computational and simulational work to date. Topics include: advances in computational methods; parallel algorithms and applications; fracture, brittle/ductile behavior and large-scale defects; thermodynamic stability of materials; surfaces and interfaces of materials; and complex materials simulations.
