The nearest neighbor Heisenberg ferromagnetic ranks among the oldest and most fundamental models of quantum many body effects. It has long been established that in one dimension quantum fluctuations lead to a quantum disordered ground state with fractional excitations called spinons." In two dimensions, the ground state of the Heisenberg model displays static order and to first approximation the dynamics can be described as semi-classical spin waves. Through theoretical advances the author demonstrates that at high energy around particular points in reciprocal space these semi-classical spin-waves deconfine into fractional excitations akin to the one-dimensional spinons. He thereby provides the first explanation of a long-standing experimental observation. In the second half of his thesis Bastien Dalla Piazza develops a unified description of the magnetic excitation spectra of a range of cuprate parent compounds to the high temperature superconductors.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053MagnetismMagnetic materialsQuantum computersSpintronicsQuantum theoryOptical materialsElectronicsMaterialsMagnetism, Magnetic Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/P25129Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070Quantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Optical and Electronic Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z12000Magnetism.Magnetic materials.Quantum computers.Spintronics.Quantum theory.Optical materials.ElectronicsMaterials.Magnetism, Magnetic Materials.Quantum Information Technology, Spintronics.Quantum Physics.Optical and Electronic Materials.538.44Dalla Piazza Bastienauthttp://id.loc.gov/vocabulary/relators/aut805088MiAaPQMiAaPQMiAaPQBOOK9910254637103321Excitation Spectra of Square Lattice Antiferromagnets2541011UNINA04502nam 2200841 a 450 991082338630332120251116152843.09786611320829978178268604017826860459781281320827128132082X97804707035020470703504978140516514314051651469780470756935047075693497804707566900470756691(CKB)1000000000405668(EBL)350895(SSID)ssj0000126205(PQKBManifestationID)11142339(PQKBTitleCode)TC0000126205(PQKBWorkID)10030006(PQKB)10700406(Au-PeEL)EBL350895(CaPaEBR)ebr10233141(Au-PeEL)EBL4956948(CaONFJC)MIL132082(FINmELB)ELB179471(MiAaPQ)EBC350895(OCoLC)212126349(Perlego)2749002(EXLCZ)99100000000040566820030917d2004 uy 0engur|n|---|||||txtccrA companion to the literature and culture of the American south /edited by Richard Gray and Owen Robinson1st ed.Malden, MA Blackwell Pub.20041 online resource (666 p.)Blackwell companions to literature and culture ;23Description based upon print version of record.9780631224044 0631224041 Includes bibliographical references and index.A Companion to the Literature and Culture of the American South; Contents; Acknowledgments; Notes on Contributors; List of Plates; PART I Introduction; 1 Writing Southern Cultures; PART II Themes and Issues; 2 The First Southerners: Jamestown's Colonists as Exemplary Figures; 3 Slave Narratives; 4 Plantation Fiction; 5 The Slavery Debate; 6 Southern Writers and the Civil War; 7 Visualizing the Poor White; 8 Southern Appalachia; 9 The Southern Literary Renaissance; 10 The Native-American South; 11 Southern Music; 12 Country Music; 13 The Civil Rights Debate; 14 Southern Religion(s)15 African-American Fiction and Poetry16 Southern Drama; 17 Sports in the South; 18 The South Through Other Eyes; 19 The South in Popular Culture; PART III Individuals and Movements; 20 Edgar Allan Poe; 21 Southwestern Humor; 22 Mark Twain; 23 Ellen Glasgow; 24 Fugitives and Agrarians; 25 William Faulkner; 26 Literature of the African-American Great Migration; 27 Zora Neale Hurston; 28 Flannery O'Connor; 29 Eudora Welty; 30 Oral Culture and Southern Fiction; 31 Recent and Contemporary Women Writers in the South; 32 The South in Contemporary African-American Fiction33 Writing in the South NowPART IV Afterword; 34 Searching for Southern Identity; IndexFrom slave narratives to the Civil War, and from country music to Southern sport, this Companion is the definitive guide to the literature and culture of the American South.
