Supraleitung und Tieftemperaturphysik 1

What it is about

In this module you will learn the fundamental phenomena, theories and applications of superconductivity. You will understand both phenomenological descriptions (London, Ginzburg–Landau) and central aspects of the BCS theory and be able to explain properties of Type-I and Type-II superconductors as well as their relevance for applications.

What you will be able to do

Describe the historical development of superconductivity research
Name fundamental properties of superconductors and evaluate them for applications
Explain the behavior of superconductors in external magnetic fields; difference between Type I / Type II
Represent thermodynamic properties of superconductors
State London and Ginzburg–Landau theories and apply them to the Meissner effect, fluxoid quantization and characteristic length scales
Explain basics of BCS theory
Describe flux-line pinning and its significance for critical currents
Outline fundamental properties of high-temperature superconductors
Name relevant applications of superconductivity

What the module consists of

VorlesungPresentation of the thematic contents; conveyance of concepts and connections (board work, projector)
ÜbungDeepening and application of the material using problem examples and calculation tasks

Teaching method

VorlesungSystematic presentation of the contents with cross-references, integration into scientific discussions to promote analytical-physical thinking
ÜbungPractice and application of learned material on concrete tasks in preparation for the module examination

What you should already know

Grundkenntnisse der Festkörperphysik / Kondensierten Materierecommended
Grundkenntnisse der Quantenmechanikrecommended

Assessment

Written examUnderstanding questionsCalculation tasks

Oral examination of 25 minutes duration. The exam exemplary checks the competencies listed in the learning goals through comprehension questions and sample calculations. Typical exam questions will address properties, theories (London, Ginzburg–Landau, BCS), magnetic field behavior, flux quantization, Josephson effects, critical currents and high-temperature superconductors. (No information on aids or weighting in the present text.)
