Key Thinkers on Space and Place
No full textIn this new edition of Key Thinkers on Space and Place, editors Phil Hubbard and Rob Kitchin provide us with a fully revised and updated text that highlights the work of over 65 key thinkers on space and place. Unique in its concept, the book is a comprehensive guide to the life and work of some of the key thinkers particularly influential in the current 'spatial turn' in the social sciences.
Providing a synoptic overview of different ideas about the role of space and place in contemporary social, cultural, political and economic life, each portrait comprises:
• biographical information and theoretical context
• an explication of their contribution to spatial thinking
• an overview of key advances and controversies
• guidance to further reading
With 14 additional chapters including entries on Saskia Sassen, Tim Ingold, Cindi Katz and John Urry, the book covers ideas ranging from humanism, Marxism, feminism and post-structuralism to queer-theory, post-colonialism, globalization and deconstruction presenting a thorough look at diverse ways in which space and place has been theorized. An essential text for geographers, this now classic reference text is for all those interested in theories of space and place, whether in geography, sociology, cultural studies, urban studies, planning, anthropology, or women's studies

No full textTim Di Muzio on 'Sabotage'
No full textIn a series of essays published in 2013 and 2014 on capitaspower.com, political economist Tim Di Muzio explored the concept of ‘sabotage’ as it applies to capitalist power. I recently rediscovered these essays and was so impressed by them that I have reposted them here as a single piece.
About the author: Tim Di Muzio is a researcher at the University of Wollongong. He is the author of numerous books, including Debt as power, Carbon capitalism, and The 1% and the Rest of us

The Sage Companion to the City
No full text'This book pulls together an exceptional range of literature in addressing the complexity of contemporary patterns and processes of urbanization. It offers a rich array of concepts and theories and is studded with fascinating examples that illustrate the changing nature of cities and urban life' - Paul Knox, University Distinguished Professer, Virginia Tech University, USA 'The SAGE Companion to the City is a tour-de-force of contemporary urban studies. At once a stocktake, showcase and springboard for scholarly approaches to cities and city life, the editors have assembled a cohesive and convincing set of lucid, insightful and critical essays of great quality. Eschewing grand theory and deadening encyclopediasm, the contributors refresh both longstanding concerns and explore new themes in ways both brilliantly accessible to newcomers and satisfying to the cognoscenti' - Robert Freestone, University of New South Wales, Australia Organized in four sections The SAGE Companion to the City provides a systematic A-Z to understanding the city that explains the interrelations between society, culture and economy. Each chapter is illustrated with key extracts from the literature: " Part One: Histories: explains: power; religion; science and technology; modernity; the landscape of the city. " Part Two: Economies and Inequalities: explains: work and leisure; globalisation; innovation and the economy; and the role of the state "Part Three: Communities: explains: migration and settlement; segregation and division; civility; house and home; housing and homelessness. " Part Four: Order and Disorder: explains: politics and policy; planning and conflict; law and order; surveillance and terror. An accessible guide to all areas of urban studies; the text offers both a contemporary cutting edge reflection and measured historical and geographical reflection on urban studies. It will be essential reading for students of any discipline interested in the city as an object of study
Dynamical effects and disorder in ultracold bosonic matter
No full textIn this thesis, various aspects on the theoretical description of ultracold bosonic atoms in optical lattices are investigated. After giving a brief introduction to the fundamental concepts of BECs, atomic physics, interatomic interactions and experimental procedures in chapter (1), we derive the Bose-Hubbard model from first principles in chapter (2). In this chapter, we also introduce and discuss a technique to efficiently determine Wannier states, which, in contrast to current techniques, can also be extended to inhomogeneous systems. This technique is later extended to higher dimensional, non-separable lattices in chapter (5). The many-body physics and phases of the Bose-Hubbard is shortly presented in chapter (3) in conjunction with Gutzwiller mean-field theory, and the recently devised projection operator approach. We then return to the derivation of an improved microscopic many-body Hamiltonian, which contains higher band contributions in the presence of interactions in chapter (4). We then move on to many-particle theory. To demonstrate the conceptual relations required in the following chapter, we derive Bogoliubov theory in chapter (5.3.4) in three different ways and discuss the connections. Furthermore, this derivation goes beyond the usual version discussed in most textbooks and papers, as it accounts for the fact, that the quasi-particle Hamiltonian is not diagonalizable in the condensate and the eigenvectors have to be completed by additional vectors to form a basis. This leads to a qualitatively different quasi-particle Hamiltonian and more intricate transformation relations as a result. In the following two chapters (7, 8), we derive an extended quasi-particle theory, which goes beyond Bogoliubov theory and is not restricted to weak interactions or a large condensate fraction. This quasi-particle theory naturally contains additional modes, such as the amplitude mode in the strongly interacting condensate. Bragg spectroscopy, a momentum-resolved spectroscopic technique, is introduced and used for the first experimental detection of the amplitude mode at finite quasi-momentum in chapter (9). The closely related lattice modulation spectroscopy is discussed in chapter (10). The results of a time-dependent simulation agree with experimental data, suggesting that also the amplitude mode, and not the sound mode, was probed in these experiments. In chapter (11) the dynamics of strongly interacting bosons far from equilibrium in inhomogeneous potentials is explored. We introduce a procedure that, in conjunction with the collapse and revival of the condensate, can be used to create exotic condensates, while particularly focusing on the case of a quadratic trapping potential. Finally, in chapter (12), we turn towards the physics of disordered systems derive and discuss in detail the stochastic mean-field theory for the disordered Bose-Hubbard model
First person - Tim Petzold
Full text linkFirst Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping researchers promote themselves alongside their papers. Tim Petzold is first author on ‘ Connexin 41.8 governs timely haematopoietic stem and progenitor cell specification’, published in BiO. Tim conducted the research described in this article while a PhD student in Julien Bertrand's lab at the Department of Pathology and Immunology, Faculty of Medicine, University of Geneva, Switzerland. He is now a postdoc in the lab of Holger Gerhardt at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association, Berlin, Germany, investigating developmental biology – previously his focus was on how blood stem cells develop and now it has shifted to how the vascular system develops
