Towards a loop representation for quantum canonical supergravity
Daniel Armand-Ugon, Rodolfo Gambini, Octavio Obregon +1
We study several aspects of the canonical quantization of supergravity in terms of the Asthekar variables. We cast the theory in terms of a connection and we introduce a l…
The space of states of quantum gravity in terms of loops and extended loops: some remarks
Cayetano Di Bartolo, Rodolfo Gambini, Jorge Griego +1
This article reviews the status of several solutions to all the constraints of quantum gravity that have been proposed in terms of loops and extended loops. We discuss pitfalls of…
Fermi-Bose Transmutation for Stringlike Excitations of Maxwell-Higgs Systems
H. Fort, R. Gambini
We show that a closed Nielsen-Olesen string in presence of a point scalar source exhibits the phenomenon of Fermi-Bose transmutation. This provides physical support to previous cla…
