Quantum Field Theory on quantized Space-Time
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Wednesday 24 February 2010
from 11:00 to 12:00
at FA31
Speaker : Harald Grosse (University of Vienna)
Abstract : In order to improve the problems of four-dimensional quantum field theory it was suggested to include "gravity effects" through quantizing space-time. The canonical deformation is particularly simple, but the resulting models suffer from the UV/IR-mixing. We found a way to handle this problem and obtain a renormalizable model for which the Landau problem is solved. At the self duality point it is almost solvable. We point out that these models fulfill the wedge locality property.
