A topological invariant in the context of the loop representation of the massive Kalb-Ramond-Klein-Gordon model
E. Iñiguez, M. Freire, L. Leal +1
We employ the Dirac procedure to quantize the self-dual massive Kalb-Ramond-Klein-Gordon model in dimensional spacetimes. The canonical fields are expressed in terms of -s…

Traversable wormholes with multiple unstable critical curves
A. Rueda, E. Contreras
The number and position of unstable critical curves, as well as the nature of the accretion disk around compact objects, play a fundamental role in their optical appearance. Identi…
