Описание: Using the thin film of light, the optical near field, that is localized on the surface of a nanometric material has removed the diffraction limit as a barrier to imaging on the nano- and atomic scales. But a paradigm shift in the concepts of optics and optical technology is required to understand the instrinsic nature of the near fields and how best to exploit them. Professors Ohstu and Kobayashi crafted Optical Near Fields on the basis of their hypothesis that the full potential for utilizing optical near fields can be realized only with novel nanometric processing, functions, and manipulation, i.e., by controlling the intrinsic interaction between nanometer-sized optical near fields and material systems, and further, atoms. The book presents physically intuitive concepts and theories for students, engineers, and scientists engaged in research in nanophotonics and atom photonics.

Описание: The era of the personal computer has, without doubt, permanently altered our life style in a myriad of ways. The "brain" of the personal computer is the microprocessor (together with RAM and ROM) which makes the decisions needed for the computer to perform in the desired manner. The microprocessor continues to evolve as increasingly complex tasks are required.
While not sharing the limelight of the microprocessor, the "heart" of the personal computer, namely the power supply, is equally important since without the necessary source of power the microprocessor would be a useless piece of silicon. The power supply of twenty years ago was much different than its modem day equivalent. At the dawn of the personal computer era in the late 1970s, de power was obtained from a simple diode bridge.
However, the need for smooth, regulated DC at low voltage required at the same time both a bulky input transformer and a large dc side ftlter. Those computer fans present at the birth of this industry can remember the large boxes housing our Altair, Cromemco and Northstar computers which was made necessary largely because of the huge power supply. It is not well appreciated but certainly true that the huge sucess of the Apple II computer in those days was due, at least in part, to the relatively slim proftle of the machine.
This sleek appearance was largely due to the adoption of the then new and unproven switched mode power supply.

Описание: Quantum measurement (Le., a measurement which is sufficiently precise for quantum effects to be essential) was always one of the most impor- tant points in quantum mechanics because it most evidently revealed the difference between quantum and classical physics.

Описание: Devoted to the theory of quantum measurements, an area that has attracted much attention because of its applications for quantum information technology, this work concentrates on the physical nature of quantum measurements and the behaviour of measured (open) quantum systems, but conceptual problems are also treated.
Light and Vacuum presents a synthesis of selected fundamental topics of electromagnetic wave theory and quantum electrodynamics (QED) and analyzes the main theoretical difficulties encountered to ensure a coherent mathematical description of the simultaneous wave-particle nature of light, put in evidence by the experiments. The notion and the role of the quantum vacuum, strongly related to light, are extensively investigated.
Classical electrodynamics issued from Maxwell's equations revealed the necessity of introducing the notion of volume for an electromagnetic wave to stand entailing precise values of cut-off wavelengths to account for the shape and dimensions of the surrounding space. Conversely, in QED, light is considered to be composed of point particles disregarding the conceptual question on how the frequency of oscillating electric and magnetic fields may be attributed to a point particle.
To conciliate these concepts, the book provides a comprehensive overview of the author's work, including innovative contributions on the quantization of the vector potential amplitude at a single photon state, the non-local simultaneous wave-particle mathematical representation of the photon and finally the quantum vacuum. The purpose of the advanced elaborations is to raise questions, give hints and answers, and finally aspire for further theoretical and experimental studies in order to improve our knowledge and understanding on the real essence of Light and Vacuum.

Описание: This book shows how Bohmian mechanics overcomes the need for a measurement postulate involving wave function collapse. Quantum stochastic trajectories (in the Bohmian sense) and their role in basic quantum processes are discussed in detail.
