Langue: Anglais
Remark: Pas donné en 2024-25. Cours donné en alternance une année sur deux.
Summary
This course provides a rigorous introduction to the ideas, methods and results of classical statistical mechanics, with an emphasis on presenting the central tools for the probabilistic description of infinite lattice systems.
Content
The goals of this course are to present
- the probabilistic description of large systems with interacting components,
- the mathematical description of phase transitions occuring in certain discrete models (Curie-Weiss, Ising model, long-range models, etc.)
- the general theory of infinite-volume Gibbs measures (the so-called Dobrushin-Lanford-Ruelle approach)
If times permits, and depending on the interest of the participants, we consider the peculiar properties of certain models with an underlying continuous symmetry (Gaussian free field, Mermin-Wagner Theorem for O(n) models).
This course is companion to the course ``lattice models'', where discrete models
are also considered, but with an emphasis on different aspects.
The lectures will be largely based on the book Statistical mechanics of lattice systems; a concrete mathematical introduction, by S. Friedli and Y. Velenik (Cambridge University Press, 2017)
