Advanced methods for physics and Quantum physics (Quantum physics)

The course aims to provide the basic mathematical tools and formalism necessary to obtain a quantum description of physical systems, and to discuss their application in predicting quantum phenomena, effects and properties characterizing systems such as the hydrogen and helium atoms, elementary molecule and matter-radiation models, the electromagnetic field, and systems of identical particles.

Students are expected 1) to achieve an effective understanding of the fundamental concepts and formal tools of Quantum Mechanics, 3) to develop ability in using them in the study of quantum systems, and 3) to develop a correct approach to the investigation of quantum systems. These achievements are certainly important for subsequent courses such as solid-state and condensed-matter physics, field theory, quantum statistical mechanics, nuclear physics.

Advanced methods for physics and Quantum physics (Quantum physics)

The knowledge of differential calculus, linear algebra concepts, vector-space theory and matrix diagonalization is required as well as the knowledge of the principles, laws and theorems of classical Mecahnics and electromagnetism.

Modalitą di esame: Prova orale obbligatoria;

Advanced methods for physics and Quantum physics (Quantum physics)

The exam is oral and consists of three questions concerning different topics of the course. Each question corresponds to a score of 10 out of 30 marks. The goal, in general, is to test the knowledge of the course program. These questions aim to evaluate the understanding of students concerning 1) the methodology used to quantize classical systems, 2) the significant properties and effects that characterize physical systems as a consequence of the quantization process and 3) the mathematical tools used to develop quantum mechanics. To this end one of the three question is focused on proving/discussing some theorem or general property characterizing quantum systems and the mathematical formalism of quantum mechanics. The other questions are devoted to discuss the quantization of physical systems for some specific case and/or to determine quantum effects and physical properties of interest emerging from this process.
