OVERVIEW

"Elementi e Applicazioni di Fisica Moderna" (EAFM, code 90693) is a 7 credits worth class held during the second semester of the First year of the "Laurea Magistrale". Lectures are held in Italian. Study material for subscribing students can be found on the AulaWeb website.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides a basic knowledge on several topics concerning modern physics, with a particular emphasis on quantum mechanics and some topics of special relativity. The aim is stimulating interest and comprehension of several physical phenomena related to these topics and to highlight important applications, especially in the field of the structure of matter.

AIMS AND LEARNING OUTCOMES

The student should acquire a knowledge of the fundamental quantum and relativistic phenomena and their role in shaping the principal physical and chemical phenomena (e.g. the electronic structer of atoms) as well as how general purpose devices (such as lasers), innovative technologies (such as the GPS) and even advanced instrumentation (such as electron microscopes) work.

TEACHING METHODS

Traditional: oral lectures and examples worked out by teachers.
