Lecturer :
Alejandro Silhanek
Language(s) of instruction :
French language
Organisation and examination :
Teaching in the first semester, review in January
Units courses prerequisite and corequisite :
Prerequisite or corequisite units are presented within each program
Course contents :
This course presents an introduction to superconductivity with particular attention on superconductors of low dimensionality and the manipulation of quantized units of flux (so called fluxonics).
Some of the concepts that will be tackled are: - Perfect electrical conductivity - London model - Basic concepts of the microscopic theory (BCS) - Fluxoid quantization - Vortex structures - Thermodynamics of superconductors (Ginzburg-Landau) - Critical fields - Interaction between vortices - Surface effects - Trapping and periodic pinning - Self Organized criticality in Superconductors (Bean Model) - Vortex avalanches - Confinement effects in superconductors - Vortex ratchets and other rectification effects - Superconductor-ferromagnet hybrid systems
Learning outcomes of the course :
By the end of the course, the students will be able: * To know and understand the electric and magnetic properties of superconductors as well as the main difference between a superconductor and a perfect conductor. * To understand how the confinement effects modify the ground state and the response of a superconducting system. * To understand the influence of the material microstructure on the conduction properties. * To know and understand the techniques used for visualizing the quantized magnetic flux. * To know and understand the way of controlling or manipulating the quantized magnetic flux.
Prerequisite knowledge and skills :
It is convenient to have basic knowledge of mathematics and solid state physics.
Planned learning activities and teaching methods :
-The time schedule is available at the web page of the ULg
- The course consist of 15 classes of 2 hours.
Mode of delivery (face-to-face ; distance-learning) :
Recommended or required readings :
The slides of the course will be distributed via email at he end of each class.
