Investigation of the microscopic behavior of Mott insulators by means of the density functional theory and many-body methods
No full textThe objective of this work is twofold. First, we explore the performance of the density functional theory (DFT) when it is applied to solids with strong electronic correlations, such as transition metal compounds. Along this direction, particular effort is put into the refinement and development of parameterization techniques for deriving effective models on a basis of DFT calculations. Second, within the framework of the DFT, we address a number of questions related to the physics of Mott insulators, such as magnetic frustration and electron-phonon coupling (Cs2CuCl4 and Cs2CuBr4), high-temperature superconductivity (BSCCO) and doping of Mott insulators (TiOCl). In the frustrated antiferromagnets Cs2CuCl4 and Cs2CuBr4, we investigate the interplay between strong electronic correlations and magnetism on one hand and electron-lattice coupling on the other as well as the effect of this interplay on the microscopic model parameters. Another object of our investigations is the oxygen-doped cuprate superconductor BSCCO, where nano-scale electronic inhomogeneities have been observed in scanning tunneling spectroscopy experiments. By means of DFT and many-body calculations, we analyze the connection between the structural and electronic inhomogeneities and the superconducting properties of BSCCO. We use the DFT and molecular dynamic simulations to explain the microscopic origin of the persisting under doping Mott insulating state in the layered compound TiOCl

Constructing the Cyberterrorist: Critical Reflections on the UK Case
No full textThis book maps and analyses the official British construction of the threat of cyberterrorism. By using interpretive discourse analysis, this book identifies ‘strands’ from a corpus of policy documents, statements and speeches from UK ministers, MPs and peers, between 12 May 2010 and 24 June 2016. The book examines how the threat of cyberterrorism was constructed in the UK, and what this securitisation has made possible. The author makes novel contributions to the Copenhagen School’s ‘securitisation theory’ framework by outlining a ‘tiered’ rather than monolithic audience system; refining the ‘temporal’ and ‘spatial’ conditioning of a securitisation with reference to the distinctive characteristics of cyberterrorism; and, lastly, by detailing the way in which popular fiction can be ascribed agency to ‘fill in’ an absence of ‘cyberterrorism’ case studies. He also argues that the UK government’s classification of cyberterrorism as a ‘Tier One’ threat created a central strand upon which a discursive securitisation was established
