exercises Tuesday, 16:15-17:00, Seminarraum 3.12

syllabus semiconductor surfaces and interfaces, 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 introduce the audience to the physics of quantum transport in electronic nanostructures and electron spin qubits, discussing among other topics spin qubits in GaAs. 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 introduce 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.

preliminary meeting / Vorbesprechung Thursday (23.2.2012), 9:15-10:00 Uhr, Room 3.12

Lecture Schedule and Content, FS 2012

Exercise Schedule and Content, FS 2012

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.

Projects and Presentations, FS12

Presentations should be no longer than about 20 to 25 minutes, plus 5 to 10 minutes for questions. 
Goal of the presentation is to explain to your fellow classmates the topic you have chosen 
as clearly and as concisely as possible while keeping a critical attitude towards the reported research.
List of available topics (below) will be modified / adapted, but will vaguely consist of the topics listed below.

Topics with more than one article: 
choose one article for in-depth presentation, mention highlights of other paper(s).
