Arbitrary black-string deformations in the black string-black hole transitions

Matthew Anderson, Luis Lehner, Jorge Pullin

We study the possible black string-black hole transition by analyzing the structure of the apparent horizon for a large family of time-symmetric initial data. We observe that, as j…

Realistic clocks, universal decoherence and the black hole information paradox

Rodolfo Gambini, Rafael Porto, Jorge Pullin

Ordinary quantum mechanics is formulated on the basis of the existence of an ideal classical clock external to the system under study. This is clearly an idealization. As emphasize…

No black hole information puzzle in a relational universe

Rodolfo Gambini, Rafael Porto, Jorge Pullin

The introduction of a relational time in quantum gravity naturally implies that pure quantum states evolve into mixed quantum states. We show, using a recently proposed concrete im…

Variational derivation of exact skein relations from Chern--Simons theories

Rodolfo Gambini, Jorge Pullin

The expectation value of a Wilson loop in a Chern--Simons theory is a knot invariant. Its skein relations have been derived in a variety of ways, including variational methods in w…

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…

Knot theory and quantum gravity in loop space: a primer

Jorge Pullin

These notes summarize the lectures delivered in the V Mexican School of Particle Physics, at the University of Guanajuato. We give a survey of the application of Ashtekar's variabl…
