Course Outline: (1) Fermi Liquid Theory (FLT) -- Conceptual background -- physics of e;ectronic
repulsion, Fermi liquid parameters, renormalization of physical ovservables in the framework of FLT. Possible breakdown of FLT, e.g. in (a) low dimensions, (b) Strong correlations. (2) Strongly correlated electronic systems --???? Mott insulators, Metal-Insulator transition etc. Hubbard Model as a minimal model for studying strong correlations, Notions of wigner x??tal, spin??-charge separation etc. (3) Superconductivity (SC) -- Microscopic theory (BCS), density of states and meissner effect within BCS framework. Beyond BCS theory and a bit of high Tc phenomenology, SC from strong correln in contrast with electron??-phonon SC in metals. (4) Basics of Quantum Magnetism -- Hubbard Model and magnetism, Stoner Ferromagnetism, Superexchange and Antiferromagnetism, Mermin-Wagner theorem. (5) Disorder and Localization Physics --???? extended vs. localized state, weak??and strong?? localization, scaling theory of localization. (6) Interacting Bosonic system and superfluidity -- Feynman theory, Mean field treatment, GP equation, superfluid density vs. condensate fraction, supersolidity. (7) Brief intro to QHE (8) Basics pf Bosonization and low dimensional systems Prerequisites: Basic CMP (currently 3rd yr) and Basic Statistical Mechanics (PH3201) or equivalent. Familiarity with concepts taught in advanced statistical mechanics (PH4203/5203) and Many-Body Physics is desirable. |
