The course is meant to give the theoretical basis needed to understand nonequilibrium quantum phenomena, particularly concerning electrons, photons and phonons. The corresponding evolution equations will be derived, and the linear response to perturbations, which includes fluctuation-dissipation relations, and the modern theory of fluctuations of observables in nonequilibrium systems will be illustrated. 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.

Expected knowledge:
- theory of nonequilibrium quantum systems and of their response to perturbations
- models of nano-structured materials of interest in the design of accurate sensors
Expected competences and skills:
- ability to handle analytic and modeling techniques to treat nonequilibrium systems
- ability to apply the acquired knowledge to the design of sensors
- ability to communicate in a clear and unambiguous way theoretical issues related to the design and manufacture of smart sensors both in writing and oral form to both specialists and non- specialists;
- development of self-learning skills, allowing the students to continue to autonomously learn new techniques and to design methodologies of investigation not necessarily during the classes.

Mathematics and physics notions common to the bachelor programs in science and technology, as well as in the first year of the present Master program. For instance, basic notions of quantum physics, of classical mechanics and thermodynamics, and the mathematics for quantum mechanics (algebra, differrential equations, integration theory, complex variables) are required. Also, notions of statistical mechanics and information theory will be useful.

Written essay on a subject related to the material of the classes.
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.

Consistently with the goals of the course, the exam aims at assessing the students' ability in dealing with the mathematical formalism of quantum mechanics at at an advanced level, and with its applications to formulate hypotheses and models to solve practical problems of interest in science and technology. The exams consists of a written essay on a subject related to the material of the classes, and it lasts 45 minutes. Two questions will be proposed, and the student will choose one. Each question will take the form: "Within the framework of (one or two of the six chapters of the course) illustrate the main concepts and equations, and describe applications of interest in science and technology". During the exam, students will be allowed to consult the material made available during the course. The maximum grade is 32, which corresponds to 30L. It is obtained by correctly reporting on all the crucial points of the chosen subject. In case of lower grade, the student may require to continue the exam orally, and the result will be either incremented or decremented, depending on the oral part of the exam. This oral part will involve both theoretical questions and exercises, and may at most contribute three (3) points to the total, while it may lead to fail the exam, if it reveals serious flaws in the student's preparation.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
