Bose-Einstein condensation, superfluidity, and superconductivity are quantum mechanics made visible. They mark the boundary between the classical and the quantum worlds, and they show the macroscopic role of quantum mechanics in condensed matter. This book presents these phenomena in terms of particles, their positions, and their momenta, giving a concrete visualisation and description that is not possible with traditional wave functions. A single approach that bridges the classical-quantum divide provides new insight into the role of particle interactions in condensation, the nature of collisions in superfluid flow, and the physical form of Cooper pairs in high-temperature superconductors. High-temperature superconductivity is explored with quantum statistical mechanics, which links it to Bose-Einstein condensation. Identifying a new mechanism for Cooper pairing, this explains the differences between the low- and high-temperature superconducting regimes and the role of the molecular structure of the conductor. The new perspective offered by this book on Bose-Einstein condensation, superfluidity, and high-temperature superconductivity gives particle-based explanations as well as mathematical and computational methods for these macroscopic quantum phenomena so that readers understand the role of particle interactions and structure in the physics of these phenomena. This book will appeal to undergraduate and graduate students, lecturers, academics, and scientific researchers in the fields of Bose-Einstein condensation and condensates, superfluidity, and superconductivity. It will also be of interest to those working with thermodynamics, statistical mechanics, statistical physics, quantum mechanics, molecular dynamics, materials science, condensed matter physics, and theoretical chemistry. Key Features: · Explores Bose-Einstein condensation with new evidence for multiple condensed states and novel Monte Carlo simulations for interacting bosons · Establishes the thermodynamic nature of condensed bosons from an analysis of fountain pressure measurements, including that they carry energy and entropy, and the thermodynamic principle of superfluid flow · Derives equations of motion for condensed bosons, and performs molecular dynamics simulations of the viscosity with molecular trajectories that give rise to superfluidity · Identifies the mechanism for electron pairing in high-temperature superconductivity
State Hiking Series Each guide includes: - Hikes suited to every ability - Accurate directions to popular as well as less-traveled trails - Up-to-date trail descriptions with mile-by-mile directional cues - Detailed trail maps and GPS coordinates - Difficulty ratings, average hiking times, and best hiking seasons for each hike - Trail Finder for best hikes with dogs, children, great views, or wildlife viewing - Information on fees and permits, contacts, events and attractions, restaurants and accommodations, canine compatibility, and more - Zero-impact and wilderness safety tips and techniques *** This second edition of Hiking Indiana adds several new trails to the choice selection in this guide. It points readers to the often-overlooked trove of natural treasures across the Hoosier State, from the living sand dunes on the shores of Lake Michigan to the glacial lakes of the northeast to the rugged topography of the southern hill country.
Looks at the history of the greatest performances by pitchers in the history of baseball including perfect games, near-misses, no-hitters, and the 20-strikeout games, highlighting such pitchers as Johnny Vander Meer, Nolan Ryan, and Roger Clemens.
The first academic work to provide an historical account and explanation of the development of this extended region to the east of Johannesburg since its origins at the end of the nineteenth century. From the time of the discovery of gold and coal until the turn of the twenty-first century, the region comprised a number of distinctive towns, all with their own histories. In 2000, these towns were amalgamated into a single metropolitan area, but, unlike its counterparts across the country, it does not cohere around a single identity. Drawing on a significant body of academic work as well as original research by the authors, the book traces and examines some of the salient historical strands that constituted what was formerly known as the East Rand and suggests that, notwithstanding important differences between towns and the racial fragmentation generated by apartheid, the region’s history contains significant common features. Arguably, its centrality as a major mining area and then as the country’s engineering heartland gave Ekurhuleni an overarching distinctive economic character.
