Learning objectives


Knowledge and understanding:
At the end of this course the student should know advanced topic in Condensed and Soft Matter Physics.

Applying knowledge and understanding:
The student should be able to analyze Condensed Matter Physics phenomena and to interpret them on the basis of the mathematical formulation of the physical laws. Beyond the methodologic tools, the course provides the students with an advanced language for Condensed Matter Physics, allowing them to read and understand advanced texts and scientific literature.

Making judgments:
By the end of the course, students should have improved their abilities to analyze Condensed Matter Physics phenomena with critical attitude, being able to apply the correct methodology to understand them.

Communication skills:
The student should be able to expose topics of Condensed Matter Physics effectively. In particular, they must be able to introduce these topics in a clear and accessible way, in order to dialogue with specialists and to translate complex concepts in a language understandable to non-specialists.

Learning skills:
The student should have acquired the learning skills related to advanced Condensed Matter Physics topics, which are necessary to study autonomously advanced texts and scientific literature.

Prerequisites


Quantum Mechanics; fundaments of Condensed Matter Physics: Atomic and Molecular structure, Crystal structures, Electronic states in solids; Basic concepts of quantum chemical calculations, basic chemistry, and statistical mechanics.

Teaching methods


Slides will be used to convey the most important messages of the theory lectures and will be available on the Elly platform.
Teaching activities will be in person.

Assessment methods and criteria


Oral examination, focusing on the knowledge and understanding of the topics discussed during the lectures.
Being an annual course, it is possible to take half-term examinations focusing on the topics of the two parts of the course, separately. The final vote is then produced basing on the arithmetic average of the votes obtained in the oral examinations of each module of the course.
