Macroscopic Quantum Phenomena And Coherence In Superconducting Networks

This volume is a review on the recent progresses done in the understanding of the physics of the superconducting arrays. It consists of five sessions:All the topical contributions go well beyond those characteristics of the condensed matter physics and offer links to the domains of the nonlinear science, complex systems and statistical mechanics.

Exploring the Quantum/Classical Frontier - Recent Advances in Macroscopic Quantum Phenomena

Macroscopic quantum phenomena (MQP) occur in a number of different systems. The majority of MQP research is done with electromagnetic circuits. The occurrence of MQP in alternative systems, the effects of the environment on MQP, the implications of MQP for measurement theory and quantum mechanics are discussed. This proceedings should therefore provide a nice balance of up-to-date results of MQP research, along with discussion of its implications and possible applications.

Develops the basic material necessary to understand the quantum dynamics of macroscopic variables. Ideal for graduate students and researchers.

This volume is a collection of papers from the fourth meeting of the International Symposium on Mesoscopic Superconductivity and Spintronics held at NTT Atsugi, Japan. Research in these fields has advanced a great deal since the previous meeting, largely because these fields have drawn much attention from the viewpoint of new quantum phenomena and quantum information technology. Mesoscopic superconductivity has been developed in new fields, such as a ferromagnet/superconductor junction, the proximity effect in unconventional superconductors, macroscopic quantum tunneling in high-Tc superconductors, quantum modulation of superconducting junctions and superconducting quantum bits. The book also covers transport and spins in nano-scale semiconductor structures such as quantum dots and wires, quantum interference and coherence and order in exotic materials, and some papers on quantum algorithm. This book adequately provides an overview of recent progress in mesoscopic superconductivity.

This is a graduate text on functional analysis. After presenting the fundamental function spaces and their duals, the authors study topics in operator theory and finally develop the theory of distributions up to significant applications such as Sobolev spaces and Dirichlet problems. Along the way, the reader is presented with a truly remarkable assortment of well formulated and interesting exercises, which test the understanding as well as point out many related topics. The answers and hints that are not already contained in the statements of the exercises are collected at the end of the book.

The main focus of the book is to present the effects of nanostructuring on superconducting critical parameters. Optimizing systematically flux and condensate confinement in various nanostructured superconductors, ranging from single nano-cells to their huge arrays, critical fields and currents can be increased up to their theoretical limits, thus drastically improving the potential for practical applications of nanostructured superconductors.
