lectures Thursdays, 10:15-12:00 Uhr, Room 1.09

exercises Tuesdays, 16:15-17:00 Uhr, Room 3.12, 1st exercise March 8, 2011

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, electron spin resonance, spin qubits, quantum computation. syllabus pdf

for: 6. semester bachelor and masters students in nanoscience and physics. physics III and condensed matter physics lecture is a prerequisite

credit points 2 credit points lecture and (optional) 2 credit points exercises.
Lecture is a two hours per week course, no problem sets, final presentation with number grade 1-6.
The exercises (pass/fail) will consist of reading a series of scientific publications relevant to class, meeting one hour per week where papers discussed by the students in depth.

purpose of this lecture is to bring the audience up to date on current experimental research in the field of quantum transport through nanostructures, focusing mainly on quantum dots in GaAs, spin-quibts in coupled dots and quantum computation. 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 semester on topics that can be chosen by students from a selection. There will be no problem sets, but moderate amounts of reading as preparation for lectures 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.

Exercise Schedule and Content, FS 2011

Organization of the exercises: As a preparation for the exercises, the students thoroughly read the one or two papers assigned before the exercise, see list below for a schedule of papers. The assigned papers are typically 3-4 pages long. It is expected that every student has at least two questions ready as a basis or starting point for a discussion. In class, the papers are discussed in detail. Focus is on depth, not breadth. In every exercise class, one student is randomly picked to be the discussion leader / mediator. To assist the discussion, the discussion leader prepares slides containing the graphs of the paper. The exercise is pass fail, based on individual preparedness.
