THREE-DIMENSIONAL MODELING

Course objectives

The course aims to provide basic knowledge in the field of modern physics starting from Quantum mechanics postulates, to condensed matter physics phenomena with a special focus on nanotechnology applications. Expected learning outcomes: Knowledge and understanding (Dublin descriptor I): Understanding the limits of classical mechanics and acquisition of the basic postulates of quantum mechanics. Applying knowledge and understanding (descriptor II): Applications of the quantum approach to specific problems: the potential well, the harmonic oscillator and the hydrogen atom. Making judgements (descriptor III): Ability to evaluate analogies and differences between the results obtained with the quantum models and the predictions based on classical physics. Ability to establish the limits of validity of an approximated model in the classical or quantum regime. Communication skills (descriptor IV) At the end of the course the student must have acquired a good language property, especially with regards to a specific scientific terminology, in order to clearly communicate their knowledge. Learning skills (descriptor V): Construction of theoretical bases for the study of the quantum properties of materials.

Exam mode
Intermediate written exam on the topics of the first module composed of 4 open questions about theory to evaluate the knowledge and understanding of basic concepts (20% of the total grade) and one numerical exercise to evaluate the ability to apply the acquired knowledge to specific problems (10 %). Intermediate written exam on the topics of condensed matter physics (see second module description for details) will contribute for 30% of the total grade Final oral exam ( 40% of the total grade): - discussion of both intermediate tests in to evaluate the knowledge and understanding ability of the students to judge and correct their mistakes by improving the knowledge autonomously. - Verification of the ability to apply the acquired knowledge in the field of modern physics to the most common nanoscale phenomena. - Verification on language property and clarity of presentation
