Current seminars

In addition to the Vienna relativity seminars, the calendar above sometimes contains other events of interest to members of the relativity group. The seminars of the Vienna relativity group are listed below.

Location (unless indicated otherwise): Währinger Str. 17
- Room 218 on the 2nd floor for standard seminars, and
- Common room, first floor, for lunch seminars. Unless explicitly stated otherwise, the regular (not-lunch) relativity seminars take place in Room 218 2nd floor, Währingerstrasse 17.

The Mathematical Physics Seminars take place on Tuesdays at 14.15.

The Particle Physics Seminars take place on Tuesdays at 16.15.

  • Thursday, October 12, 14:00, joint relativity-mathematical physics seminar, Harald Grosse (Vienna): Quantum field theory models on noncommutative spaces

Abstract: In order to improve QFT in 4 D we (HG and Raimar Wulkenhaar) studies models over quantized space-times. They become Matrix models, which share all interesting features of a QFT: A graphical description with Feynman rules, power counting dimension, regularisation and renormalisation, divergence of the perturbation series.- We report on models, where we can give exact non-perturbative formulae for all renormalised correlation functions. We describe a map, which projects these matrix correlation functions to Schwinger functions of an ordinary quantum field theory. The Schwinger 2-point functions satisfies in some models the Osterwalder-Schrader axioms.

  • Thursday, October 19, 14:00, Florian Steininger (Vienna): Exoplanets and general relativity

Abstract: The first confirmation of the theory of general relativity was given by the perihelion precession of the planet mercury in our own solar system. In recent decades, we have expanded our scope to many new extra-solar planetary systems, making use of rapidly improving observational techniques. This has opened up the possibility of observing the effects of general relativity in distant systems, giving additional confidence in our understanding of the universe.
I will present the findings of my bachelor thesis, concerning the impact of such a precession upon observable quantities in the system, as well as the methods used to extract them from the raw data.
