Strongly Interacting Quantum Systems, Volume 2

This book presents a unique approach to non-perturbative Quantum Many Body Physics. Instead of focusing on the standard approaches, it builds our understanding of these systems by using methods that traditionally pertain to few-body physics, allowing for strong interactions to be tackled from a solid and well-understood foundation. The covered topics range from exactly solvable models, which are known to require only two-particle input, and Bose-Fermi mappings, which are fully non-perturbative, to the physics of few-body systems embedded in many-body media. The book is intended as a detailed advanced tutorial for young and experienced researchers that want to delve deeper into this exciting field.Key Features: Many worked examples of representative quantum systems, together with their physical interpretations and the main consequences of their solutions. Set of problems at the end of each chapter, not meant to complement the theory, but to give the reader dexterity in using the...
