Spacetime symmetries and geometric diffusion
Marc Basquens, Antonio Lasanta, Emanuel Mompó +2
We examine relativistic diffusion through the frame and observer bundles associated with a Lorentzian manifold . Our focus is on spacetimes with a non-trivial isometry group…
Separable Hilbert space for loop quantization
J. Fernando Barbero G., Tomasz Pawłowski, Eduardo J. S. Villaseñor
We discuss, within the simplified context provided by the polymeric harmonic oscillator, a construction leading to a separable Hilbert space that preserves some of the most importa…
Detailed black hole state counting in loop quantum gravity
Ivan Agullo, J. Fernando Barbero G., Enrique F. Borja +2
We give a complete and detailed description of the computation of black hole entropy in loop quantum gravity by employing the most recently introduced number-theoretic and combinat…
The combinatorics of the SU(2) black hole entropy in loop quantum gravity
Ivan Agullo, J. Fernando Barbero G., Enrique F. Borja +2
We use the combinatorial and number-theoretical methods developed in previous work by the authors to study black hole entropy in the new proposal put forward by Engle, Noui and Per…
BF Actions for the Husain-Kuchar Model
J. Fernando Barbero G., Eduardo J. S. Villaseñor
We show that the Husain-Kuchar model can be described in the framework of BF theories. This is a first step towards its quantization by standard perturbative QFT techniques or the…
In Search of Local Degrees of Freedom in Quadratic Diff-invariant Lagrangians
J. Fernando Barbero G., Eduardo J. S. Villaseñor
We show that local diff-invariant free field theories in four spacetime dimensions do not have local degrees of freedom.
