Learning outcomes
Knowledge

The student who successfully completes the course will be able to demonstrate general knowledge of: i) equilibrium and non-equilibrium statistical physics, ii) principles of condensed matter physics, iii) light-matter interaction.

Assessment criteria of knowledge

During the oral exam the student must be able to demonstrate his/her knowledge of the course material using the appropriate terminology. He/she will also be asked to apply such knowledge to new / unexpected situations to deduce the main general trends expected from physical considerations.

Methods: final oral exam

 

Skills

The student will be able to use statistical methodologies and techniques (classical and quantum) to solve simple thermodynamical problems and to apply them to relevant problems in the physics of condensed matter and gases and of their interaction with the electromagnetic field.

Assessment criteria of skills

The course features an interactive approach in which students are involved in discussions with the teacher, also concerning new results appearing in the scientific literature. Basic excersises / questions are an integral part of the lessons to verify the degree of comprehension.

Behaviors

The student is expected to develop the capability of tackling complex physical problems relying on physical intuition rather than on a brute force mathematical approach. In particular he/she should be able to assess which contributions and processes are relevant and which can be neglected (also based on statistical considerations) draw the necessary approximations, and understand their limits of application.  

Assessment criteria of behaviors

These will be assessed during the lessons, posing problems and discussing suggested solutions (also through student competitions via teaching sofware like Socrative). During the exams it will be explicitly requested to avoid use of mathematics in several cases. 

Prerequisites

Knowledge of general physics (mechanics and thermodynamics) is necessary. Basic understanding of quantum mechanics (Wave functions, probability amplitudes, perturbation theory) is highly recommended. 

Co-requisites

The Quantum Mechanics course can be followed in parallel. It is highly recommended to prepare for the final exam after having prepared the quantum mechanics one.

Prerequisites for further study

 Mandatory for all courses of the Laurea Magistrale

Non-attending students info

An advance meeting with the teacher is recommended. Notes and a detailed page to page bibliography can be made available. 

Modalità d'esame

Esame orale che di solito tratta due argomenti distinti, uno più statistico, l'altro più relativo agli stati quantistici e all'interazione. All'allievo verrà chiesto di iniziare a discutere sull'argomento, e durante la discussione si chiederà di spiegare l'origine delle sue affermazioni e come le conoscenze enunciate possono essere applicate a una nuova situazione non affrontata durante le lezioni.

Assessment methods

Oral exam that will typically deal of two distinc topics, one more statitical, the other more quantum states / interaction. The student will be asked to start discussing on the subject, during which discussion he/she will be asked to explain the origin of his/her statements and how they can be applied to a new situation not faced during the lessons.
