Linear operators in Hilbert space play a fundamental role in the formulation of quantum theory. This book offers a self-contained presentation of the most important tools and methods from Hilbert space theory, with particular focus on the spectral theory of self-adjoint operators. But it also goes further by describing some applications in quantum mechanics, in particular the analysis of Schrödinger operators and quantum scattering theory. The final two chapters are devoted to Mourre's conjugate operator method and some of its consequences for scattering theory. The text gives complete proofs and includes numerous exercises.
Based on a one-year course offered to advanced undergraduates, the text will be especially useful to students with some background in quantum mechanics, to whom it will provide a fundamental treatment of some of the basic ideas of applied Hilbert space theory; in addition, the book will prove invaluable to lecturers of basic and advanced quantum mechanics and to mathematical physicists in general, including those who work in spectral and scattering theory.

Photovoltaic technology has now developed to the extent that it is close to fulfilling the vision of a “solar-energy world,” as devices based on this technology are becoming efficient, low-cost and durable. This book provides a comprehensive treatment of thin-film silicon, the most prevalent PV material, in terms of its semiconductor nature, starting out with the physical properties, but concentrating on device applications.
The use of neural implants for stimulation and recording show excellent promise in restoring certain functions to the central nervous system; and neuroprostheses remain one of the most important tools of neuroscientists for the elucidation of the brain’s function.
Barely five weeks after the opening of the Rolex Learning Center, the verdict fell—the building’s architects, Kazuyo Sejima and Ryue Nishizawa (SAANA), were announced the winners of the 2010 Pritzker Prize, the most prestigious prize in architecture.
The dye-sensitized solar cell (DSC) is a photovoltaic converter that mimics natural photosynthesis. Like green plants and algae it uses a molecular absorber, the dye, to harvest sunlight and generate electric charges.
