Motivation:

Superconductivity is a fascinating phenomenon t
hat 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,
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 application
s 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 10

of the
Earths magnetic field and a millio
nth 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 th
e necessary theory for modeling superconducting devices.


Organization:

Lectu
res, Home assignments
, Demonstrations.



Prerequisites:

Classical electrodynamics



Literature:



A complete
Compendium

will be delivered during the course to registered stu
dents.

Examination








Examination:

Home assignments (optional), Oral examination. Grade level: 3(G) =30%, 4(VG)=60%,
5(MVG)=80%.



You will get bonus points for home assignm
ents, which will be counted at the oral exam.
Maximum bonus is 30%, which means that you could pass the course with the grade 3(G)
if you have made all the homework.
