Quantum Theory of Bulk and Nanostructure Crystals

This book focuses on bulk and nanostructure crystals, and specifically discusses possible crystal lattices, their reciprocal lattices, and the Bragg relation for determining crystal structure. It describes band theory in independent electron approximation using the usual perturbation quantum theory, as well as how the internal electric field of the lattice periodic potential affects degenerate states at the Brillouin zone boundaries by using the Stark effect, which leads to energy bands separated by energy gaps. The book also discusses low-dimensional systems and nanostructures using the free electron model and tight binding model. The band structure and wave function of graphene, graphene nanoribbons, single-wall carbon nanotubes, and double-wall carbon nanotubes are obtained. Additionally, nanostructure vibrations are discussed. This text is for graduate and undergraduate students, as well as researchers who are interested in working on different condensed matter physics subjects. We use simple methods to introduce and explain the initial concepts of crystal structure physics to undergraduate students.

A Jurisprudence of Movement

Law moves, whether we notice or not. Set amongst a spatial turn in the humanities, and jurisprudence more specifically, this book calls for a greater attention to legal movement, in both its technical and material forms. Despite various ways the spatial turn has been taken up in legal thought, questions of law, movement and its materialities are too often overlooked. This book addresses this oversight, and it does so through an attention to the materialities of legal movement. Paying attention to how law moves across different colonial and contemporary spaces, this book reveals there is a problem with common law’s place. Primarily set in the postcolonial context of Australia – although ranging beyond this nationalised topography, both spatially and temporally – this book argues movement is fundamental to the very terms of common law’s existence. How, then, might we move well? Explored through examples of walking and burial, this book responds to the challenge of how to live with a contemporary form of colonial legal inheritance by arguing we must take seriously the challenge of living with law, and think more carefully about its spatial productions, and place-making activities. Unsettling place, this book returns the question of movement to jurisprudence.
