Spherically symmetric loop quantum gravity: Schwarzschild spacetimes with a cosmological constant
Esteban Mato, Javier Olmedo, Sahil Saini
We provide a quantization of the Schwarzschild spacetime in the presence of a cosmological constant, based on midisuperspace methods developed in the spherically symmetric sector o…
Analysis of improved dynamics of non-rotating charged black holes
Florencia Benitez, Esteban Mato, Javier Olmedo
We provide the quantization of a charged black hole. We consider a redefinition of the scalar constraint in order to render the algebra of constraints as a Lie algebra. We apply lo…
Axisymmetric gravity in real Ashtekar variables: the quantum theory
Rodolfo Gambini, Esteban Mato, Jorge Pullin
In a previous paper we formulated axisymmetric general relativity in terms of real Ashtekar--Barbero variables. Here we proceed to quantize the theory. We are able to implement Thi…
Classical axisymmetric gravity in real Ashtekar variables
Rodolfo Gambini, Esteban Mato, Javier Olmedo +1
We formulate axisymmetric general relativity in terms of real Ashtekar--Barbero variables. We study the constraints and equations of motion and show how the Kerr, Schwarzschild and…
