Lorentz and CPT violation in QED revisited: A missing analysis
Oswaldo M. Del Cima, Jakson M. Fonseca, Daniel H. T. Franco +1
We investigate the breakdown of Lorentz symmetry in QED by a CPT violating interaction term consisting of the coupling of an axial fermion current with a constant vector field ,…
No parity anomaly in massless QED3: a BPHZL approach
Oswaldo M. Del Cima, Daniel H. T. Franco, Olivier Piguet +1
In this letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED_3 frequently claimed in the literature. As long as perturbative quantum fiel…
The Hilbert space of Chern-Simons theory on the cylinder. A Loop Quantum Gravity approach
Clisthenis P. Constantinidis, Gabriel Luchini, Olivier Piguet
As a laboratory for loop quantum gravity, we consider the canonical quantization of the three-dimensional Chern-Simons theory on a noncompact space with the topology of a cylinder.…
