Understanding Bose-Einstein Condensation, Superfluidity, and High-Temperature Superconductivity

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

India's Energy Revolution

India is the third-largest emitter of greenhouse gases, which makes it an important player whose climate mitigation actions and inactions are closely scrutinised. This book studies developments in India's energy system from a governance perspective. It presents a unique compilation and synthesis of research findings that capture achievements, shortcomings, and persistent and transient challenges of India's transition towards a net-zero economy by 2070. The book grounds its analysis in domestically formulated goals and reflects on dynamics at the structural level of India's multi-scalar innovation system, by highlighting the influencing factors of energy system status and change. It presents the perspectives and positions of different actor groups, studies the market and business, and discusses cases influenced by existing or changing institutions across the whole spectrum of energy resources from fossil to non-fossil fuels and respective technologies. The volume will be useful for students and researchers in energy governance, energy policy and economics, socio-technical transition studies, energy systems engineering, sustainable development, and environmental studies. It will also be of interest to policymakers and investors.

Fentale

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Fentale is one of the 180 woredas in the Oromia Region of Ethiopia. Part of the Misraq Shewa Zone located in the Great Rift Valley, Fentale is bordered on the southeast by the Arsi Zone, on the southwest by Boset, on the northwest by the Amhara Region, and on the northeast by the Afar Region. The administrative center of Fentale is Metehara; other towns include Addis Ketema. Most parts of this woreda range from 900 to 1000 meters above sea level; Mount Fentale is the highest point.

Hans Henrik Andersen

Hans Henrik Andersen (b. 1937 Frederiksberg, Denmark) is Professor at the Niels Bohr Institute of the University of Copenhagen (emeritus since 2004). He is co-editor of the scientific journal "Nuclear Instruments and Methods in Physics Research B". He has made important contributions to various fields of atomic physics and solid state physics, especially in the field of the stopping power of matter for fast charged particles. The accuracy (0.3-0.5%) of his measurements is unsurpassed even today (2006).
