Physics and beyond — presentations, lectures and articles

Presentation for childrenThis is a collection of different presentations, teaching materials in the form of courses, lectures and articles related to past teaching duties.

Physics of financial markets

Winter 2008. Overhead transparencies to a presentation on selected topics of financial markets and pricing models. The scope is rather diverse and does not assume prior knowledge in economics. Basic statistical understanding is a plus for this topic, however.

Eigenvalues of(f) GPUs

Winter 2008. With the availability of graphics processors for scientific computations, it makes a lot of sense to use these devices for lattice QCD calculations. In this lecture I explore the possibility to use GPUs for calculations of eigenvectors and eigenvalues, an ingredient to computing disconnected diagrams and other quantities. A sample program employing NVIDIA's CUDA framework is available separately on request.

The holographic principle

Winter 2008. A very brief, basic introduction to the idea of the holographic principle. As a particle physicist I have always struggled to understand the abstract concepts underlying this fundamental identity. Here I give a very simple argument why the holographic principle is interesting and how it can be applied to actual physics like the strong interaction.

Nuclear physics long range plan, Pt. III

Winter 2008. The long range plan of nuclear physics by the US community. Chapter on nuclei and equation of state review, pages 57 – 74. Although the long range plan targets a general audience, this review presentation is quite specific to an audience of fellow researchers and advanced students.

Software engineering tools

Summer 2008. Overhead transparencies of a presentation at NTU to introduce students to tools for software engineering. Version management, document generation and coding guidelines are reviewed, the software development model to write specifications first is discussed.

Introduction to parallel computing for lattice gauge theory

Summer 2008. Overhead transparencies of an introductory overview on parallel computing as needed by lattice gauge theory computations. While these calculations only require a subset of the power available through most frameworks, they will benefit from the optimization of what is actually needed. This overview accompanies the formal lecture series on hadron structure.

Other articles

Raytracing & visualization — basics and usage

Summer 2008. Application of raytracing and and volume-rendered visualization methods for results of scientific computations. The class focuses on open-source software only and requires only a general physics background.

The structure of hadrons and their computation on the lattice

Winter 2007. Series of lectures introducing hadronic structure, related observables, and their computation on the lattice. Conceptual problems related to the LSZ formalism and Haag's theorem are discussed. Forward propagators are being introduced, from there the technique of sequential propagators is developed. Specific software for handling this problem is introduced, a step-by-step introduction to Chroma for hadronic structure is given.

Introduction to electrodynamics, University of Regensburg

Summer 2002. The exercises, their solutions, and the final exam are available to course instructors upon request only. Please send me your request and indicate the year you have participated as a teaching assistant by private mail.

Seminar über Quantencomputing

Winter 2000. Seminar at the Fachbereich Physik at the University of Wuppertal in October 2000. My Introductory lecture is available as a gzipped Postscript file.

Computer Theoreticum, University of Wuppertal

Summer 2000. The course material from 2000 and later years are available to participants of the class only. I am sorry, but this restriction has not been set in place by myself. If you are a participant of these classes, please send me your name and the semester you have attended by mail and I will can send you the material privately.

High-school and student projects

This is a collection of several of my own projects I did when I was a student at high-school and University. The main purpose is a reminder to myself of what I can still learn from what I did back then. I found that many lessons were not really of technological value, but rather about mistakes I made when marketing myself and my projects. These projects with a short summary (and in a few cases also the code itself) are listed on this page.
