However, many important questions remain to be answered. Their intrinsically quantum mechanical nature and the large (usually effectively infinite) number of spins in macroscopic materials often leads to unexpected or counter-intuitive results and insights. Spin systems are not only the basic models for a whole host of magnetic materials but they are also important as prototypical models of quantum systems. Low dimensional systems (as treated in this primer), in 2D and especially 1D, have been particularly fruitful because their simplicity has enabled exact solutions to be determined in many cases. These exact solutions contain many highly nontrivial features. This book was inspired by a set of lectures on quantum spin systems and it is set at a level of practical detail that is missing in other textbooks in the area. It will guide the reader through the foundations of the field. In particular, the solutions of the Heisenberg and XY models at zero temperature using the Bethe Ansatz and the Jordan-Wigner transformation are covered in some detail. The use of approximate methods, both theoretical and numerical, to tackle more advanced topics is considered. The final chapter describes some very recent applications of approximate methods in order to show some of the directions in which the study of these systems is currently developing. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v816 606 $aQuantum physics 606 $aSolid state physics 606 $aQuantum computers 606 $aSpintronics 606 $aLow temperature physics 606 $aLow temperatures 606 $aPhase transitions (Statistical physics) 606 $aQuantum Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19080 606 $aSolid State Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25013 606 $aQuantum Information Technology, Spintronics$3https://scigraph.springernature.com/ontologies/product-market-codes/P31070 606 $aLow Temperature Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25130 606 $aPhase Transitions and Multiphase Systems$3https://scigraph.springernature.com/ontologies/product-market-codes/P25099 615 0$aQuantum physics. 615 0$aSolid state physics. 615 0$aQuantum computers. 615 0$aSpintronics. 615 0$aLow temperature physics. 615 0$aLow temperatures. 615 0$aPhase transitions (Statistical physics). 615 14$aQuantum Physics. 615 24$aSolid State Physics. 615 24$aQuantum Information Technology, Spintronics. 615 24$aLow Temperature Physics. 615 24$aPhase Transitions and Multiphase Systems. 676 $a539.7/25 700 $aParkinson$b John B$4aut$4http://id.loc.gov/vocabulary/relators/aut$01023466 702 $aFarnell$b Damian J.

Analyzing their entangled histories and systems of devotion, Tracey E. Hucks and Dianne M. Stewart articulate how these religions were criminalized during slavery and colonialism yet still demonstrated autonomous modes of expression and self-defense. In Volume II, Orisa, Stewart scrutinizes the West African heritage and religious imagination of Yoruba-Orisa devotees in Trinidad from the mid-nineteenth century to the present and explores their meaning-making traditions in the wake of slavery and colonialism. She investigates the pivotal periods of nineteenth-century liberated African resettlement, the twentieth-century Black Power movement, and subsequent campaigns for the civil right to religious freedom in Trinidad. Disrupting syncretism frameworks, Stewart probes the salience of Africa as a religious symbol and the prominence of Africana nations and religious nationalisms in projects of black belonging and identity formation, including those of Orisa mothers. Contributing to global womanist thought and activism, Yoruba-Orisa spiritual mothers disclose the fullness of the black religious imagination's affective, hermeneutic, and political capacities."--$cProvided by publisher. 410 0$aReligious cultures of African and African diaspora people. 517 3 $aOrisa :$eAfricana nations and the power of black sacred imagination 606 $aOrisha religion$zTrinidad and Tobago$zTrinidad$xHistory 606 $aReligion and sociology$zTrinidad and Tobago$zTrinidad$xHistory 606 $aReligions$xAfrican influences 606 $aBlack people$zTrinidad and Tobago$zTrinidad$xReligion$xHistory 606 $aCults$xLaw and legislation$zTrinidad and Tobago$zTrinidad$xHistory 606 $aReligion and law$zTrinidad and Tobago$zTrinidad$xHistory 606 $aPostcolonialism$zTrinidad and Tobago$zTrinidad 607 $aTrinidad$xReligion$xAfrican influences 615 0$aOrisha religion$xHistory. 615 0$aReligion and sociology$xHistory. 615 0$aReligions$xAfrican influences. 615 0$aBlack people$xReligion$xHistory. 615 0$aCults$xLaw and legislation$xHistory. 615 0$aReligion and law$xHistory. 615 0$aPostcolonialism 676 $a299.60972983 686 $aREL000000$aSOC002010$2bisacsh 700 $aStewart$b Dianne M.$01276161 801 0$bNcD 801 1$bNcD 906 $aBOOK 912 $a9910617313503321 996 $aObeah, Orisa, and religious identity in Trinidad$93007177 997 $aUNINA LEADER 01066nam0 22002891i 450 001 UON00069801 005 20231205102346.265 010 $a03-335-6069-8 100 $a20020107d1991 |0itac50 ba 101 $aeng 102 $aGB 105 $a|||| ||||| 200 1 $aArms and the man$eDr. Gerald Bull, Iraq and the supergun$fWilliam Lowther 210 $aLondon$cMacmillan$d1991 215 $a298 p.$cill.$d25 cm 606 $aIRAQ$xPolitica militare$3UONC019795$2FI 606 $aBULL, Gerald$3UONC019796$2FI 620 $aGB$dLondon$3UONL003044 676 $a320.9567$cPOLITICA E GOVERNO DELL'IRAQ$v21 700 1$aLOWTHER$bWilliam$3UONV043852$0657795 712 $aMacmillan & Co.$3UONV247335$4650 801 $aIT$bSOL$c20240220$gRICA 899 $aSIBA - SISTEMA BIBLIOTECARIO DI ATENEO$2UONSI 912 $aUON00069801 950 $aSIBA - SISTEMA BIBLIOTECARIO DI ATENEO$dSI IRQ Afr V 004 $eSI AA 14521 5 004 996 $aArms and the man$91160864 997 $aUNIOR
