This monograph presents an intuitive theory of trial wave functions for strongly interacting fermions in fractional quantum Hall states. The correlation functions for the proposed fermion interactions follow a novel algebraic approach that harnesses the classical theory of invariants and semi-invariants of binary forms. This approach can be viewed as a fitting and far-reaching generalization of Laughlin's approach to trial wave functions. Aesthetically viewed, it illustrates an attractive symbiosis between the theory of invariants and the theory of correlations. Early research into numerical diagonalization computations for small numbers of electrons shows strong agreement with the constructed trial wave functions.The monograph offers researchers and students of condensed matter physics an accessible discussion of this interesting area of research.

This book provides the basis for a two-semester graduate course on solid-state physics. The first half presents all the knowledge necessary for a one-semester survey of solid-state physics, but in greater depth than most introductory solid state physics courses. The second half includes most of the important research over the past half-century, covering both the fundamental principles and most recent advances. This new edition includes the latest developments in the treatment of strongly interacting two-dimensional electrons and discusses the generalization from small to larger systems. The book provides explanations in a class-tested tutorial style, and each chapter includes problems reviewing key concepts and calculations. The updated exercises and solutions enable students to become familiar with contemporary research activities, such as the electronic properties of massless fermions in graphene and topological insulators.

Why read this book on Environmental Stress Screening If you are working in the electronic manufacturing industry and you have heard the questions: "Why did it fail in the field and not in the factory ?" The answer to this question is there was not a proper ESS program developed for this product. A good ESS program is develop from the ground up and the fallout data is tracked. The fallout data is used to alter the present ESS program. This new /altered program is tailored to the hardware and usually is less costly and should improve the product reliability. "Why can't we use the same ESS program as the other guy ?" The answer to this is you can, if you are manufacturing the exact same product. If this is the case, you must be working with the other guy. A different product requires a different ESS program. Or If you are working in the electronic manufacturing industry and you have heard the statements: "I won't do ESS, it's going to cost too much." Can you put a price on field returns or lost contracts because of poor quality ? "I don't need to ESS, I'll just be more careful during manufacturing." You can be as careful as you want. If you don't weed out the Latent defects the time bomb is ticking. Or (worst case condition) If you are working in the electronic manufacturing industry and you have heard the front door being locked for the last time because of poor Quality hardware being shipped to the customer: Unfortunately if this happens it is too late to do anything. Hopefully you will develop a strong ESS program that is cost effective, apply dynamic management of the ESS program by analyzing the fallout data and last but not least - use common sense.

Many scholars of sub-Saharan Africa agree that inward-oriented development policies have hampered economic development in the region. Quinn questions traditional explanations for the low economic growth levels of sub-Saharan African countries by showing that majority state ownership of enterprise is a sufficient condition for inward-oriented policies and that this variable is a better predictor of such policies than other current explanations in the development literature. Supporting his observations through compelling case studies, Quinn offers a major statement that will be of interest to anyone concerned about African political and economic conditions and the future welfare of African peoples struggling to come to terms with the imperatives of a changing global economy.
