Some Classic Papers 

II. Statistical Mechanics, 1st semester (4/11/02  5/2/03)
Yoseph Imry, Erel Levin
Lectures: Mondays 911, Wednesdays 45, in the Weissman Auditorium
Problems: Wednesdays 56. The problems will be given every week and they have to be submitted on a bi weekly basis (first submission: 20/11, second: 4/12, etc.).
Attending the lectures is not a must, but you have to submit ALL the problems, except when reasons such as illness or reserve service exist. This is highly recommended also for those not needing credit. The exercise grade will be a substantial part (1/3 1/2) of the final grade.
The final exam, necessary for those interested in credit, will be in writing, most probably of the "open book" type. It is highly recommended to take Prof. Levinson's course "Transport Phenomena in Metals and Semiconductors", Mondays 111, in Weissman Room A. There will be some coordination between the two courses.
Feel free to contact us at any time, at fnimry@wicc.weizmann.ac.il, or erel.levin@weizmann.ac.il.

Syllabus
 Basis of Statistical Mechanics in both the classical and the quantum cases. The equal probability rule, the microcanonical ensemble. The concept of entropy. Thermodynamic ensembles. Basic principles of thermodynamics.
 The ideal gases, the classical gas, molecular structure and degrees of freedom, spin. Ideal Fermi gas, Ideal Bose gas. Bose condensation and its modern realizations. Quantum ideal gases with internal degrees of freedom.
 Classical nonideal gases: The virial expansion, the Van der Waals equation of state, DebyeHückel theory.
 Fluctuations: Thermodynamic fluctuations and correlation functions; dynamic fluctuations;experimental detection of correlation functions.
 Quantum nonideal gases; Introduction to superfluidity. The Fermi liquid.
 Elements of classical phase transitions, the liquidgas phase transition: The Van der Waals fluid, first order transitions, continuous transitions. Magnetic phase transitions: Meanfield and Landau theory, phenomenology, breakdown of Landau theory and the Ginzburg criterion, the Heisenberg and Ising models, the lattice gas model, the energyentropy argument and the lower critical dimension, spontaneous symmetry breaking, breaking of ergodicity. Beyond meanfield: Fluctuations, the 1D Ising model, the transfer matrix method. Correlation functions, definitions of critical exponents, universality and scaling theory.
 (If time permits) Some dynamics: Temporal correlation functions. The fluctuationdissipation theorem. The Onsager relationship. Diffusion. Elementary kinetic equations.
