Course outline:Previously on ICFP Statistical Physics: I Introduction to phase transitions and critical phenomena II First order phase transitions III Critical phenomena : qualitative approaches IV Renormalisation group ideas PART B ... Towards condensed matterI Quantum Phase transitions (2.5 lectures) 1 Experiments and rationale 2 Ising model in one dimension 3 Quantum rotors Suggested reading: [S] p3 thru 8. Content: Define a quantum phase transition and identify the mechanisms playing the role of entropy. Existence of scale invariance and universality classes. Connection to classical thermal phase transitions. Coarse-grained description for continuous phase transitions. Technically: the momentum shell RG, Jordan-Wigner in d=1, Bogoliubov transformation for fermions. II Interacting atomic gases (1.5 lectures) 1 Ideal Bose gas 2 Weakly Interacting Bose gas 3 Hard-core bosons in one dimension 4 The Bose-Hubbard Model Suggested reading: [PeSm] pp 225-234; [S] pp193-202. Content: Start from atomic physics and connect to hard condensed matter by increasing the interaction strength. How is the Bose-Einstein condensation affected by interactions. Technically: Bogoliubov for bosons, RG for the Bose-Hubbard model. III Disorder, classical and quantum (2 lectures) 1 Classical diffusion in random media 2 Spin glasses 3 Localization 4 Random matrices Suggested reading: [H] pp386-397 (on random walks); [N] pp 11-22 (order parameter, replicas, in spin glasses) ; [CC] pp 1-16 (same but somewhat more mathematical). Content: Quenched vs Annealed disorder. Typical vs rare realizations. Self-averaging. Edwards-Anderson order parameter. Absence of extended states in low dimensions in the presence of disorder.
