| Course contents : | The statistical physics lecture concerns the relationship between the microscopic interaction between two particles and the macroscopic physical properties of a large number of these particles.
Part I: Equilibrium
Gibbs ensemble approach is detailed and consequently the microcanonical, canonical and grand-canonical ensemble are described. Afterwards, the quantum statistics of Fermi-Dirac and Bose-Einstein are explained and compared. The Bose-Einstein condensation is finally described.
Part II: Phase transition
The link between micro- and macro-worlds is emphasized. First order and second order transition are compared. The Landau model is explained and its limitation defined by the Ginzburg-Landau criterium. Finally, spin models (Ising) are approached and also modern techniques as Wilson's renormalization.
Part III: Percolation and diffusion. |
