Examination methods: Oral examination covering three or four of the topics chosen by the teacher among all those treated in the course. To each topic ample time is devoted to the exposition and to the discussion of possible connections with other parts of the program. This allows to ascertain how the student masters the subject.
Course unit contents: Introduction to the physics of complexity and of emergent
phenomena (general points of view of P.W. Anderson,
N. Goldenfeld, L.P. Kadanoff, ...)

Selected topics in the statistics of polymers, percolation,
fractals, and disorder. Continuous symmetries and Kosterliz Thouless transition.

Brownian motion. Mathematics of Brownian motion and
stochastic differential equations. Stochastic processes.
Statistical mechanics out of equilibrium.
Microscopic reversibility and macroscopic irreversibility.
Detailed balance in equilibrium. Onsager reciprocity relations
with examples (Seebeck and Peltier effects, etc.).
Fluctuation-response theorem, dynamic susceptivity and
fluctuation-dissipation theorem. Kramers-Kronig relations.
Microscopic basis of Brownian motion.

Thermodynamics out of equilibrium at the micro- and
nano-scales. Markovian description of non-equilibrium dynamics.
Fluctuation theorems and work identities. Generalized detailed
balance. Entropy production. Asymmetric simple exclusion and
related processes, some basic results. Theory of large deviations.
Molecular motors. Applications of Gallavotti-Cohen theorem.
Textbooks (and optional supplementary readings)
