Quantum gravity corrections to particle interactions
Luis Urrutia
An heuristic semiclassical procedure that incorporates quantum gravity induced corrections in the description of photons and spin 1/2 fermions is reviewed. Such modifications are c…

Exact Solution of the Schwinger Model with Compact U(1)
Roman Linares, Luis F. Urrutia, J. David Vergara
The exact solution of the Schwinger model with compact gauge group U(1) is presented. The compactification is imposed by demanding that the only surviving true electromagnetic degr…

The Itzykson-Zuber Integral for U(m|n)
Jorge Alfaro, Ricardo Medina, Luis F. Urrutia
We compute the Itzykson-Zuber (IZ) integral for the superunitary group U(m|n). As a consequence, we are able to find the non-zero correlations of superunitary matrices
