This book, now in its second edition, introduces readers to quantum rings as a special class of modern high-tech material structures at the nanoscale. It deals, in particular, with their formation by means of molecular beam epitaxy and droplet epitaxy of semiconductors, and their topology-driven electronic, optical and magnetic properties. A highly complex theoretical model is developed to adequately represent the specific features of quantum rings. The results presented here are intended to facilitate the development of low-cost high-performance electronic, spintronic, optoelectronic and information processing devices based on quantum rings. This second edition includes both new and significantly revised chapters. It provides extensive information on recent advances in the physics of quantum rings related to the spin-orbit interaction and spin dynamics (spin interference in Rashba rings, tunable exciton topology on type II InAs/GaAsSb quantum nanostructures), the electron-phonon interaction in ring-like structures, quantum interference manifestations in novel materials (graphene nanoribbons, MoS2), and the effects of electrical field and THz radiation on the optical properties of quantum rings. The new edition also shares insights into the properties of various novel architectures, including coupled quantum ring-quantum dot chains and concentric quantum rings, topologic states of light in self-assembled ring-like cavities, and optical and plasmon m.odes in Möbius-shaped resonators.

This book deals with a new class of materials, quantum rings. Innovative recent advances in experimental and theoretical physics of quantum rings are based on the most advanced state-of-the-art fabrication and characterization techniques as well as theoretical methods. The experimental efforts allow to obtain a new class of semiconductor quantum rings formed by capping self-organized quantum dots grown by molecular beam epitaxy. Novel optical and magnetic properties of quantum rings are associated with non-trivial topologies at the nanoscale. An adequate characterization of quantum rings is possible on the basis of modern characterization methods of nanostructures, such as Scanning Tunneling Microscopy. A high level of complexity is demonstrated to be needed for a dedicated theoretical model to adequately represent the specific features of quantum rings. The findings presented in this book contribute to develop low-cost high-performance electronic, spintronic, optoelectronic and information processing devices based on quantum rings.

In Quantum Ring Theory Wladimir Guglinski presents a radical new theory concerning the fundamental nature of physics. Hailed as a intriguing theorist by Dr. Eugene Mallove, president of the New Energy Foundation, Guglinski argues that the current understanding of physics does not put forth an accurate model of the world. Instead, Guglinski argues that we must once again consider the "aether," a notion originally put forth by Greek philosophers. By considering the nature of "aether" and its role in physical processes, Guglinski is able to put forth a theory that reconciles Quantum Physics with the Theory of Relativity. To date, no other physical theory is able to accord for the intraction between these two fundamental areas of physics. As part of Guglinski's new theory, the author presents a new model of the neutron. Guglinski's model of the neutron has been confirmed by contemporary physical experiments: The first one was made by Don Borghi and published in 1993 by the American Institute of Physics; the second experiment was made by Elio Conte and Maria Pieralice, subsequently published in the magazine Infinite Energy in 1999. Currently, other experiments around the world are being conducted to test the remainder of Guglinski's theoretical work. Quantum Ring Theory presents for the first time in a complete text the theoretical work of Wladimir Guglinski. In this volume cutting edge theoretical work in physics is presented; theoretical work which may ultimately change the very way we understand the world.

The ability to engineer the bandstructure and the wavefunction over length scales previously inaccessible to technology using artificially structured materials and nanolithography has led to a new class of electron semiconductor devices whose operation is controlled by quantum effects. These structures not only represent exciting tools for investigating new quantum phenomena in semiconductors, but also offer exciting opportunities for applications. This book gives the first comprehensive treatment of the physics of quantum electron devices. This interdisciplinary field, at the junction between material science, physics and technology, has witnessed an explosive growth in recent years. This volume presents a detailed coverage of the physics of the underlying phenomena, and their device and circuit applications, together with fabrication and growth technology.

Taking both a theoretical and observational perspective, this book is an introduction to recent developments in the field of celestial mechanics. It emphasizes the application to extended celestial bodies and devotes much attention to rotational aspects. In particular, it explains the state of art for accurate modelling of the rotation of celestial bodies such as the Earth, the Moon, and Mercury, which involves principles related to hydrodynamics and geodesy. Comparisons between the light curves of the asteroids and their rotational state are made and spatial techniques leading to the determination of the Earth's gravitational field are explained. Also, the book provides a general overview of the collisional processes in the solar system and of the dynamics of the rings. It is addressed to graduate students and researchers in space sciences and celestial dynamics.

While the field of clusters and nano-structures in the physical sciences has been actively pursued only over the past two decades, nature has known the benefits of the nanoscale for a very long time. The focus of the International Symposium on Clusters and Nano-Assemblies: Physical and Biological Systems was to explore ways in which an understanding of the unique properties of nano-scale biological systems such as proteins, enzyme reactions, RNA, and DNA can help us design novel materials composed of inorganic nano-scale systems, and how techniques developed in the physical sciences can lead to a fundamental understanding of biological systems. Bringing together the expert contributions from the conference, this book deals with the fundamental science and technology of atomic clusters, nano-structures and their assemblies in physical and biological systems. It explores in fascinating detail the manner in which finite size, low dimensionality, and reduced symmetry affect the properties of nano-assemblies.

This book demonstrates how the new phenomena in the nanometer scale serve as the basis for the invention and development of novel nanoelectronic devices and how they are used for engineering nanostructures and metamaterials with unusual properties. It discusses topics such as superconducting spin-valve effect and thermal spin transport, which are important for developing spintronics; fabrication of nanostructures from antagonistic materials like ferromagnets and superconductors, which lead to a novel non-conventional FFLO-superconducting state; calculations of functional nanostructures with an exotic triplet superconductivity, which are the basis for novel nanoelectronic devices, such as superconducting spin valve, thin-film superconducting quantum interference devices (SQUIDs) and memory-elements (MRAM). Starting with theoretical chapters about triplet superconductivity, the book then introduces new ideas and approaches in the fundamentals of superconducting electronics. It presents various quantum devices based on the new theoretical approaches, demonstrating the enormous potential of the electronics of 21st century - spintronics. The book is useful for a broad audience, including researchers, engineers, PhD graduates, students and others wanting to gain insights into the frontiers of nanoscience.
