PERIOD: APRIL - JULY The course is meant to give the theoretical basis needed to understand nonequilibrium physical phenomena, deriving the standard fluctuation-dissipation relations, linear response theory, and the modern results concerning fluctuations of observables in nonequilibrium systems. These results are of particular interest in the study of systems in conditions far away from equilibrium, and in the modern bio- and nano-technology.

1. Nonequilibrium thermodynamics: local equilibrium, balance equations and hydrodynamic equations; 2. Brownian motion and fluctuation-dissipation theorem; 3. Onsager reciprocal relations; 4. Green-Kubo relations; 5. Onsager-Machlup theory 6. ensembles and invariant measures: microscopic foundations and the role of chaos; 7. ergodic and chaotic hypotheses; 8. far from equilibrium and nanoscale systems: Equivalence and non-equivalence of ensembles; 9. trasient fluctuation relations (Evans-Searles, Jarzynski, Crooks, Hatano-Sasa); 10. steady state fluctuation relations (Evans-Cohen-Morriss, Gallavotti-Cohen); Bibliografia: D.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
