New tools for Loop Quantum Gravity with applications to a simple model
Enrique F. Borja, Jacobo Díaz-Polo, Laurent Freidel +2
Loop Quantum Gravity is now a well established approach to quantum gravity. One of the main challenges still faced by the theory is constructing a consistent dynamics which would l…
Revisiting the quantum scalar field in spherically symmetric quantum gravity
Enrique F. Borja, Iñaki Garay, Eckhard Strobel
We extend previous results in spherically symmetric gravitational systems coupled with a massless scalar field within the loop quantum gravity framework. As starting point, we take…
Dynamics for a simple graph using the U(N) framework for loop quantum gravity
Enrique F. Borja, Jacobo Diaz-Polo, Laurent Freidel +2
The implementation of the dynamics in loop quantum gravity (LQG) is still an open problem. Here, we discuss a tentative dynamics for the simplest class of graphs in LQG: Two vertic…
U(N) and holomorphic methods for LQG and Spin Foams
Enrique F. Borja, Jacobo Diaz-Polo, Iñaki Garay
The U(N) framework and the spinor representation for loop quantum gravity are two new points of view that can help us deal with the most fundamental problems of the theory. Here, w…
Learning about Quantum Gravity with a Couple of Nodes
Enrique F. Borja, Iñaki Garay, Francesca Vidotto
Loop Quantum Gravity provides a natural truncation of the infinite degrees of freedom of gravity, obtained by studying the theory on a given finite graph. We review this procedure…
U(N) invariant dynamics for a simplified Loop Quantum Gravity model
Enrique F. Borja, Jacobo Díaz-Polo, Iñaki Garay +1
The implementation of the dynamics in Loop Quantum Gravity (LQG) is still an open problem. Here, we discuss a tentative dynamics for the simplest class of graphs in LQG: Two vertic…
