Available in PDF, EPUB and Kindle. Book excerpt: The dynamical properties of solids have recently attracted renewed interest in connection with the increasing understanding of phase transitions and re lated phenomena. In particular, soft modes or, more generally, phonon 'anom alies' seem to play an important role in structural and electronic phase tran sitions, such as ferroelectric or superconducting transitions. The understanding of the mechanisms responsible for the occurrence of unusually low frequencies in phonon spectra requires a detailed analysis of the microscopic forces governing the lattice vibrations. Of particular importance is the influence of the electron lattice interaction in the adiabatic approximation which in many cases is the origin of peculiarities in the phonon self-energy. In this work the vibrational spectra of pure non-metals and of those con taining point defects are investigated. ' In these materials the interrelation be tween the pseudo-harmonic forces (determining the phonon dispersion re lations) and the non-linear anharmonic and electron-phonon forces (as they act in infrared and Raman spectra) is most obvious and can be quantitatively analysed in terms of appropriate models. The main task is to arrive at a physically correct treatment of electronic degrees of freedom, as for example in an electronic 'shell' model, which leads to the description of phonon spectra in terms of long-range polarizabilities and short-range deformabilities. The pur pose of our review is to stimulate further investigations which, we hope, will result in explicit relations between the parameters of the semi-microscopic models and the matrix elements from the electronic band structure.

This book was released on 2012-12-06 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reissue of Encyclopedia of Physics/Handbuch der Physik, Vol. XXV/2b I am very pleased that my book is now to be reprinted and rebound in a new format which should make it accessible at a modest price to students and active researchers in condensed matter physics. In writing this book I had in mind an audience of physicists and chemists with no previous deep exposure to symmetry analysis of crystalline matter, non to the use of symmetry in simplifying and refining predictions of the results of optical experiments. Hence the book was written to explain and illustrate in all necessary detail how to: 1) describe the space group symmetry in terms of space group symmetry operations; 2) obtain irreducible representations and selection rules for optical infra-red and Raman and other transition processes. On the physical side I redeveloped the traditional theory of classical and quantum lattice dynamics, illustrating how space-time symmetry designations in the equations of motion can: 1) simplify and rationalize calculations of the classical eigenvectors of the dynamical equation; 2) permit classification of the eigenstates of the quantum lattice-dynamic pro blem; 3) give specific selection rules for optical infra-red and Raman lattice processes, and thus make "go, no-go" predictions including polarization of absorbed or scattered radiation; and 4) simplify the modern many-body theories of optical processes.

This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: 159 elements only between states which differ in one of the single-electron wave functions, in short, HeR induces only one-electron transitions. The matrix elements 1mn and Pmn reduce to matrix elements between the single-electron wave functions. We are interested primarily in crystalline solids for which the band model is a good approximation. The Bloch single-electron wave function in this model has the form: N'I ili-';; U. r.;;) ( (1.14) ""nk r, =e nh\r , where n is the band index and U (r) has the periodicity of the lattice. The form of the Bloch function follows from the translational symmetry of the crystal, and the matrix elements between Bloch states are subject to the condition of wave-vector conservation: k'=k, for
Book Synopsis Light and Matter Ic / Licht und Materie Ic by : Hermann Haken

This book was released on 2013-06-29 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of the laser came into existence more than a decade ago when ScHAWLOW and TowNES showed that the maser principle could be extended to the optical region. Since then this field has developed at an incredible pace which hardly anybody could have foreseen. The laser turned out to be a meeting place for such different disciplines as optics (e.g. spectroscopy), optical pumping, radio engineering, solid state physics, gas discharge physics and many other fields. The underlying structure of the laser theory is rather simple. The main questions are: what are the light intensities (a), what are the frequencies (b), what fluctua tions occur (c), or, in other words, what are the coherence properties. Roughly speaking these questions are treated by means of the rate equations (a), the semiclassical equations (b), and the fully quantum mechanical equations (c), respectively. The corresponding chapters are written in such a way that they can be read independently from each other. For more details about how to proceed, the reader is advised to consult Chap. I.4.

Download or read book Beyond Bach written by Andrew Talle and published by University of Illinois Press. This book was released on 2017-04-07 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reverence for J. S. Bach's music and its towering presence in our cultural memory have long affected how people hear his works. In his own time, however, Bach stood as just another figure among a number of composers, many of them more popular with the music-loving public. Eschewing the great composer style of music history, Andrew Talle takes us on a journey that looks at how ordinary people made music in Bach's Germany. Talle focuses in particular on the culture of keyboard playing as lived in public and private. As he ranges through a wealth of documents, instruments, diaries, account ledgers, and works of art, Talle brings a fascinating cast of characters to life. These individuals--amateur and professional performers, patrons, instrument builders, and listeners--inhabited a lost world, and Talle's deft expertise teases out the diverse roles music played in their lives and in their relationships with one another. At the same time, his nuanced re-creation of keyboard playing's social milieu illuminates the era's reception of Bach's immortal works.

Book Synopsis Constructions of Cultural Identities in Newsreel Cinema and Television after 1945 by : Kornelia Imesch
Download or read book Constructions of Cultural Identities in Newsreel Cinema and Television after 1945 written by Kornelia Imesch and published by transcript Verlag. This book was released on 2016-12-31 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newsreel cinema and television not only served as an important tool in the shaping of political spheres and the construction of national and cultural identities up to the 1960s. Today's potent televisual forms were furthermore developed in and strongly influenced by newsreels, and much of the archived newsreel footage is repeatedly used to both illustrate and re-stage past events and their significance. This book addresses newsreel cinema and television as a medium serving the formation of cultural identities in a variety of national contexts after 1945, its role in forming audiovisual narratives of a »biopic of the nation«, and the technical, aesthetical, and political challenges of archiving and restaging cinematic and televisual newsreel.
Book Synopsis Nine Letters on Landscape Painting by : Carl Gustav Carus
Download or read book Nine Letters on Landscape Painting written by Carl Gustav Carus and published by Getty Publications. This book was released on 2002 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carl Gustav Carus (1789-1869)--court physician to the king of Saxony--was a naturalist, amateur painter, and theoretician of landscape painting whose Nine Letters on Landscape Painting is an important document of early German romanticism and an elegant appeal for the integration of art and science. Carus was inspired by and had contacts with the greatest German intellectuals of his day. Carus prefaced his work with a letter from his correspondence with Johann Wolfgang von Goethe, who was his primary mentor in both science and art. His writings also reflect, however, the influence of the German natural philosopher Friedrich Wilhelm Joseph Schelling, especially Schelling's notion of a world soul, and the writings of the naturalist and explorer Alexander von Humboldt. Carus played a role in the revolution in landscape painting taking place in Saxony around Caspar David Friedrich. The first edition appears here in English for the first time.
