Cold and Ultracold Collisions in Quantum Microscopic and Mesoscopic Systems

類似書籍推薦給您

This book describes collisions between atoms that have been cooled to extremely low temperatures by optical and evaporative cooling techniques. The author reviews the elements of the quantum theory of scattering, and summarizes the theory and experimental techniques of optical cooling and trapping. Later chapters describe applications to precision spectroscopy, the determination of atomic properties, control of inelastic collisions by laser fields, and the manipulation of Bose-Einstein condensates (mesoscopic quantum systems). Finally, it reviews the essential properties of these mesoscopic quantum systems and describes the key importance of the scattering length to condensate stability. Descriptions of experiments and theory are included.

Cold Region Hazards And Risks

【簡介】 This is a unique, timely and engaging text with wide ranging geographical coverage. The text brings together, for the first time, information about a vast array of hazards associated with ice and snow, spanning both well known phenomenon (e.g. avalanches) and the less familiar (e.g. river ice jams and ice storms) using, in many cases, material which is rarely seen outside advanced academic research books and journals. The range of ice-related hazards will be introduced and the significance of the current global warming context discussed. Broad physical models of glacial, periglacial and atmospheric cold environments are presented to provide a scientific context for discussion of the human issues of risk, vulnerability impact and mitigation. Key Features: Wide ranging geographical coverage (the Americas, Asia, Australasia, Antarctic & Europe) Localised hazards (avalanches, life storms, landslides) contrasted to those with wider reaching effects (arctic ice loss, ice sheet retreat and wide spread permafrost decay) Includes the latest developments in the field Each chapter includes hazards overview, summery, conclusions, potential projects exercise and key references Includes a supplementary website with figures from the text and further references Each chapter includes a hazards overview, summary, conclusions, potential projects exercise and key references 【目錄】
