This book covers recent developments in the understanding, quantification, and exploitation of entanglement in spin chain models from both condensed matter and quantum information perspectives. Spin chain models are at the foundation of condensed matter physics and quantum information technologies and elucidate many fundamental phenomena such as information scrambling, quantum phase transitions, and many-body localization. Moreover, many quantum materials and emerging quantum devices are well described by spin chains. Comprising accessible, self-contained chapters written by leading researchers, this book is essential reading for graduate students and researchers in quantum materials and quantum information. The coverage is comprehensive, from the fundamental entanglement aspects of quantum criticality, non-equilibrium dynamics, classical and quantum simulation of spin chains through to their experimental realizations, and beyond into machine learning applications.

Based on a multi-sited ethnographic case study on transnational care chains between Milan (Italy) and Lima, Huancayo, and Cuzco (Peru), the book explores how social inequalities are reproduced through the care practices that follow the introduction of Peruvian migrants into home-based elderly care. Anna Katharina Skornia adopts an innovative approach in combining research on transnational care and migration with a perspective on entangled inequalities. In particular, the study sheds light on the role of state regulations in contributing to these inequalities as well as their ambiguous implications from the perspectives of both caregivers and receivers.

In addition to being a poet, fiction writer, playwright, and essayist, Langston Hughes was also a globe-trotting cosmopolitan, travel writer, translator, avid international networker, and—perhaps above all—pan-Africanist. In Cultural Entanglements, Shane Graham examines Hughes’s associations with a number of black writers from the Caribbean and Africa, exploring the implications of recognizing these multiple facets of the African American literary icon and of taking a truly transnational approach to his life, work, and influence. Graham isolates and maps Hughes’s cluster of black Atlantic relations and interprets their significance. Moving chronologically through Hughes’s career from the 1920s to the 1960s, he spotlights Jamaican poet and novelist Claude McKay, Haitian novelist and poet Jacques Roumain, French Negritude author Aimé Césaire of Martinique, South African writers Es’kia Mphahlele and Peter Abrahams, and Caribbean American novelist Paule Marshall. Taken collectively, these writers’ intellectual relationships with Hughes and with one another reveal a complex conversation—and sometimes a heated debate—happening globally throughout the twentieth century over what Africa signified and what it meant to be black in the modern world. Graham makes a truly original contribution not only to the study of Langston Hughes and African and Caribbean literatures but also to contemporary debates about cosmopolitanism, the black Atlantic, and transnational cultures.

Investigates how data production and consumption territorialize the physical landscape filtered through Ireland’s role in global communications and, as told by the Irish Pavilion at the 2021 Venice Architecture Biennale, features an installation that focuses on the materiality of data infrastructure in space. As our everyday lives become increasingly entangled with data technologies, the book addresses the utopian fantasy that surrounds the Cloud, as transcending physical presence or resourcing. By bringing the physical infrastructure around data, and its impact on the environment under the spotlight, it hopes to reframe how we understand data production and highlight the myth that information technologies are hidden and without major material manifestations on the landscape. The context for the book is Ireland which has a significant historical role in the evolution of global communications and data infrastructure. In 1866, the world’s first transatlantic telegraph cable landed on the West coast of Ireland. In 1901, the inventor of the radio Guglielmo Marconi transmitted some of the world’s first wireless radio messages from Ireland across the Atlantic Ocean to Newfoundland. Today, Dublin has overtaken London as the data centre hub of Europe, hosting 25% of all available European server space. And by the year 2027, data centres are forecast to consume a third of Ireland’s total electricity demand. The book aims to raise awareness around the hardware of the global internet and Cloud services, which is interwoven with the Irish landscape—made manifest through the vast constellation of data centres, fibre optic cable networks, and energy grids that have come to populate its cities and suburbs over recent decades. The publication accompanies and supports Entanglement, the Irish Pavilion at the 17th Venice Architecture Biennale by archiving the production of the pavilion filtered through a series of poetic excerpts that describe the form, components, content and furniture that make up the installation. At the same time the book is conceived as more than just a catalog by positioning some of the cultural and spatial implications of data technologies in Ireland within a more universal context through contributions by ANNEX, the team selected to produce the pavilion, as well as invited contributors from the disciplines of Media Theory; Journalism; Computer Science, Geography; History and Architecture.
