Sommario/riassunto |
|
Describing the physical properties of quantum materials near critical points with long-range many-body quantum entanglement, this book introduces readers to the basic theory of quantum phases, their phase transitions and their observable properties. This second edition begins with a new section suitable for an introductory course on quantum phase transitions, assuming no prior knowledge of quantum field theory. It also contains several new chapters to cover important recent advances, such as the Fermi gas near unitarity, Dirac fermions, Fermi liquids and their phase transitions, quantum magnetism, and solvable models obtained from string theory. After introducing the basic theory, it moves on to a detailed description of the canonical quantum-critical phase diagram at non-zero temperatures. Finally, a variety of more complex models are explored. This book is ideal for graduate students and researchers in condensed matter physics and particle and string theory. |

Sommario/riassunto |
|
This book is the result of a study on demand-led plant variety design for changing markets in Africa, the purpose of which is to identify and share best practices in demand-led plant breeding from private and public sector breeding programmes worldwide. The intended audiences are professionals in plant breeding and related areas, such as seed production, who have interests in developing and disseminating new plant varieties as a way to increase productivity and profitability in crop agriculture, especially in Africa. The volume is also intended for use as a resource book for the education of postgraduate scholars in plant breeding and genetics, and for the continuing professional development of plant breeders. For this purpose, boxes are included in the main sections of each chapter that summarize its educational objectives and present the key messages and questions that are involved; in addition, there is a final box at the end of each chapter that summarizes its overall learning objectives. |
