Knowledge at the level of the module in experimental physics: „Physics of condensed matter“ is required.
For a successful participation an active involvement in the exercies is required.
Contents:
The students should get acquainted with the physical foundations of superconductivity. In particular they should understand how the independent individual electrons in a solid condense into a macroscopic quantum state, what is the symmetry of the order parameter, and how the order parameter is determined. An understanding of the transport properties of the superconducting ground state shall be achieved with respect to the possibilities of dissipation free transport and the realization of superconducting quantum phenomena as ultrasensitive sensors or qubits. In one or several special topics a deeper understanding of a subfield of current research in solid state physics shall be achieved forming the foundation to successfully prepare a master thesis on these topics.
The concise topics treated are: electrons in solids, BCS-theory for Cooper pair formation and condensation in the ground state, phase transition and transport properties Ginzburg-Landau description, type I and type II superconductors, the Josephson effect and its applications in ultra sensitive sensors and as voltage normal, critical currents in superconductors, superconducting magnets, superconducting qubits, high temperature superconductivity, transport in two-dimensional systems, related quantum effects as Quantum Hall effect.
