MANY-BODY PHYSICS, TOPOLOGY AND GEOMETRYAuthor(s): Siddhartha Sen, Kumar Sankar Gupta\nFormat: Hardback\nPublisher: World Scientific Publishing Co Pte Ltd, Singapore\nImprint: World Scientific Publishing Co Pte Ltd\nISBN-13: 9789814678162, 978-9814678162\nSynopsis\nThe book explains concepts and ideas of mathematics and physics that are relevant for advanced students and researchers of condensed matter physics. With this aim, a brief intuitive introduction to many-body theory is given as a powerful qualitative tool for understanding complex systems. The important emergent concept of a quasiparticle is then introduced as a way to reduce a many-body problem to a single particle quantum problem. Examples of quasiparticles in graphene, superconductors, superfluids and in a topological insulator on a superconductor are [url] mathematical idea of self-adjoint extension, which allows short distance information to be included in an effective long distance theory through boundary conditions, .
