Quantum Theory of ManyBody Systems

Product Description This Text Presents A SelfContained Treatment Of The Physics Of ManyBody Systems From The Point Of View Of Condensed Matter. The Approach, Quite Traditionally, Uses The Mathematical Formalism Of Quasiparticles And GreenS Functions. In Particular, It Covers All The Important Diagram Techniques For Normal And Superconducting Systems, Including The ZeroTemperature Perturbation Theory And The Matsubara, Keldysh And NambuGorKov Formalism, As Well As An Introduction To Feynman Path Integrals.This New Edition Contains An Introduction To The Methods Of Theory Of OneDimensional Systems (Bosonization And Conformal Field Theory) And Their Applications To ManyBody Problems.Intended For Graduate Students In Physics And Related Fields, The Aim Is Not To Be Exhaustive, But To Present Enough Detail To Enable The Student To Follow The Current Research Literature, Or To Apply The Techniques To New Problems. Many Of The Examples Are Drawn From Mesoscopic Physics, Which Deals With Systems Small Enough That Quantum Coherence Is Maintained Throughout Their Volume And Which Therefore Provides An Ideal Testing Ground For ManyBody Theories.
