I am a researcher in theoretical physics. My primary interest lies in the understanding and the mathematical description of new and exotic quantum phases of matter. This includes fractionalized spin liquids, braid statistics, topological order, quantum Hall states, topological insulators, Mott insulators, and superconductors.

List of peer-reviewed publications, talks, and preprints.
- a Casual Introduction to the Hubbard model.
- Slightly more serious stuff on a S-I-N junction.
- A note on Heinz Schulz, PRB 1986.
- A note on the Riemann-Hilbert problem and random matrix theory.
- A rewrite of my variational Monte Carlo code (no Pfaffians yet); this source goes under GLP, and please cite my papers if you extract some inspiration.
- My Diploma (Master) thesis at EPFL about a soliton in quantum field theory.
- My PhD (Doctoral) thesis on RVB approaches to high-temperature superconductivity: PDF.
- A work about the Bieri-Neumann-Strebel Invariant in group theory (German).
- And: Elemente der Signalverarbeitung.
- Teaching the Particle-Wave Duality to college students.
- A short presentation on biodiversity loss.
- My CV (possibly not up to date!).
- Teaching Wärmelehre.
Finally, you may be wondering what this is all about... so: Theoretical physics is a science locally isomorphic to mathematics.

An interesting article on a problematic aspect of modern academic research; PDF.
An interview with Richard P. Feynman at BBC (80 megs).
A short essay on "The point of being in business" which I find nice.
SVN version control (the better CVS) - a must for all programming efforts.
Note: this seems to be superseded by GIT now.
The International Institute of Physics is a good address for science in Latin America.
My uncle is a famous mathematician.
My brother is an outstanding artist.
