Organization of Lecture, SS06
weekly lectures Tue, 9-11am, Tue 2. Mai 8-10am, Thur 8-10am, NCCR room 2.04
syllabus 2D electron gas, quantum point contacts, quantum dots, conductance fluctuations, quantum phase coherence, Coulomb blockade, Kondo effect, few electron dots, spin blockade, spin relaxation, charge sensing, single spin measurement, spin manipulation and coherence, nuclear spins, spin qubits, quantum computation.
for: masters and 6. semester bachelor students in nanoscience and physics. physics III lecture is a prerequisite
2 credit points I will be teaching this "Spezialvorlesung" for about 6 weeks, i.e. only half a semester. Instead of the 2 hours per week (for the 2 points), I was thinking to hold the lecture 2 times 2 hours per week to compensate for the 6 week length
purpose of this lecture is to bring the audience up to date of current experimental research in the field of quantum transport through nanostructures, focusing mainly on quantum dots in GaAs and spin-quibts in coupled dots. The lecture will inevitably discuss some (simple) condensed matter theory but will mainly focus on experiments
structure will be a combination of lectures on my part to intruduce the basics and subsequent presentations done by students towards the end of the 6 week lecture period on topics that can be chosen by students from a small selection. There will be no problem sets, but moderate amounts home reading will be assigned. The class is pass/fail, and the evaluation will be based on the presentation given by each student taking the class for credit. Sit-ins/students auditing the class (not for credit) are welcome
