Quantum space-time of a charged black hole
Rodolfo Gambini, Esteban Mato Capurro, Jorge Pullin
We quantize spherically symmetric electrovacuum gravity. The algebra of Hamiltonian constraints can be made Abelian via a rescaling and linear combination with the diffeomorphism c…
Casimir effect in a quantum space-time
Rodolfo Gambini, Javier Olmedo, Jorge Pullin
We apply quantum field theory in quantum space-time techniques to study the Casimir effect for large spherical shells. As background we use the recently constructed exact quantum s…
Quantum shells in a quantum space-time
Rodolfo Gambini, Jorge Pullin
We study the quantum motion of null shells in the quantum space-time of a black hole in loop quantum gravity. We treat the shells as test fields and use an effective dynamics for t…
A scenario for black hole evaporation on a quantum geometry
Rodolfo Gambini, Jorge Pullin
We incorporate elements of the recently discovered exact solutions of the quantum constraints of loop quantum gravity for vacuum spherically symmetric space-times into the paradigm…
Emergence of string-like physics from Lorentz invariance in loop quantum gravity
Rodolfo Gambini, Jorge Pullin
We consider a quantum field theory on a spherically symmetric quantum space time described by loop quantum gravity. The spin network description of space time in such a theory lead…
