Canonical quantization of the electromagnetic field in arbitrary -gauge
Fernando Falceto
We carry out the canonical quantization of the electromagnetic field in arbitrary -gauge and compute its propagator. In this way we fill a gap in the literature and clarify some…
Asymptotic freedom and higher derivative gauge theories
M. Asorey, F. Falceto, L. Rachwal
The ultraviolet completion of gauge theories by higher derivative terms can dramatically change their behavior at high energies. The requirement of asymptotic freedom imposes very…
Dual branes in topological sigma models over Lie groups. BF-theory and non-factorizable Lie bialgebras
Ivan Calvo, Fernando Falceto
We complete the study of the Poisson-Sigma model over Poisson-Lie groups. Firstly, we solve the models with targets and (the dual group of the Poisson-Lie group ) corr…
Star products and branes in Poisson-Sigma models
Ivan Calvo, Fernando Falceto
We prove that non-coisotropic branes in the Poisson-Sigma model are allowed at the quantum level. When the brane is defined by second-class constraints, the perturbative quantizati…
Poisson-Dirac branes in Poisson-Sigma models
Ivan Calvo, Fernando Falceto
We analyse the general boundary conditions (branes) consistent with the Poisson-sigma model and study the structure of the phase space of the model defined on the strip with these…
Poisson reduction and branes in Poisson-Sigma models
Ivan Calvo, Fernando Falceto
We analyse the problem of boundary conditions for the Poisson-Sigma model and extend previous results showing that non-coisotropic branes are allowed. We discuss the canonical redu…
