Aim

Motivation:
Superconductivity is a fascinating phenomenon that allows us to observe
quantum mechanical effects at the macroscopic scale. A tremendous
importance of superconductivity for fundamental science can be seen from
the fact that there are at least 12 Nobel laureates in physics
(including two in 2003), who obtained the
price for research related to superconductivity. Besides being of
tremendous interest in themselves and vehicles for development key
concepts and methods in theoretical physics, superconductors have found
important applications in modern society. Those range from high power
applications and strong superconducting magnets used in medicine,
diagnostics and particle accelerators; to most sensitive quantum devices
capable of measuring about a trillionth part of the Earths magnetic
field and a millionth part of the electron charge.

Aim and Goal:
The course is aiming to provide a basic knowledge of the theory of
superconductors and the Josephson effect and their applications in
cryoelectronics. It introduces a number of basic concepts and develops
the necessary theory for modeling superconducting devices.

Goal

See above.
