OVERVIEW

This class has the following aims:

  • to investigate and understand the physical mechanisms of the superconductivity
  • to present the main superconducting materials and their properties
  • to how the main applications of superconductivity

AIMS AND CONTENT

LEARNING OUTCOMES

The course presents the basic phenomenological and theoretical aspects to understand the properties of superconducting materials. The main objective is to provide the indispensable elements for interpreting the behavior of superconductors and their applications starting from the phenomenological theories of Ginzburg and Landau and from the microscopic theories (BCS).

AIMS AND LEARNING OUTCOMES

  • Students will be provided with the means needed to understand the properties of supeconducting materials.
  • The mechanisms of superconductivity will be understood via theoretical and phenomenological models suitable to identify the microscopic parameters which define the superconducting properties in metals.
  • The superconducting materials will be studied highlighting also the scientific research which led to their discovery.
  • The main experimental techniques for the characterization of the superconducting properties will be described and understood also through lab experiments.
  • In order to better understand the main applications of superconductivity, visits at industries in Genova operating in the field of superocnductivity will be origanized.

PREREQUISITES

There are no prerequisites. It is suggested to follow the Physics of Matter 2 course

TEACHING METHODS

Lectures (48h) on blackboard with power point slides projection where necessary. Visits to research laboratories and to local industries (Columbus Superconductors/ASG-Superconductors).

EXAMS

EXAM DESCRIPTION

The student agrees with the teacher to deepen a specific topic treated in class with the help of review articles selected by the teacher. The student prepares a presentation on the chosen topic to be presented at the blackboard exam or with powerpoint presentations.
The exam is oral and consists of the discussion of an agreed topic and two or more questions about the rest of the course.

ASSESSMENT METHODS

The oral exam lasts about 30 minutes. It consists in the presentation on the blackboard or by powerpoint slides of the argument chosen by the student and by its subsequent discussion with the teachers. Furthermore, a fixed number of questions (normally two questions) on other topics of the main course should be answered by the student.

The proposed discussion let the teacher assess the student learning, his/her synthesis and critical skills and the achievement of the course training objectives. If these objectives have not been achieved, the student is invited to deepen his/her knowledge of the course topics with the help of more supporting materials and/or more explanations/suggestions by the teachers.

The exam dates are not set in the calendar, but are requested by the student and agreed with the teachers.
