Quantum Einstein-Rosen waves: Coherent states and n-point functions
J. Fernando Barbero G., Iñaki Garay, Eduardo J. S. Villaseñor
We discuss two different types of issues concerning the quantization of Einstein-Rosen waves. First of all we study in detail the possibility of using the coherent states correspon…
Generating functions for black hole entropy in Loop Quantum Gravity
J. Fernando Barbero G., Eduardo J. S. Villaseñor
We introduce, in a systematic way, a set of generating functions that solve all the different combinatorial problems that crop up in the study of black hole entropy in Loop Quantum…
Black hole state counting in Loop Quantum Gravity: A number theoretical approach
Ivan Agullo, J. Fernando Barbero G., Jacobo Diaz-Polo +2
We give a practical method to exactly compute black hole entropy in the framework of Loop Quantum Gravity. Along the way we provide a complete characterization of the relevant sect…
Unitary evolution of free massless fields in de Sitter space-time
Daniel Gómez Vergel, Eduardo J. S. Villaseñor
We consider the quantum dynamics of a massless scalar field in de Sitter space-time. The classical evolution is represented by a canonical transformation on the phase space for the…
Quantum unitary evolution of linearly polarized S^1\times S^2 and S^3 Gowdy models coupled to massless scalar fields
J. Fernando Barbero G., Daniel Gómez Vergel, Eduardo J. S. Villaseñor
The purpose of this paper is to study in detail the problem of defining unitary evolution for linearly polarized S^1 x S^2 and S^3 Gowdy models (in vacuum or coupled to massless sc…
Hamiltonian Dynamics of Linearly Polarized Gowdy Models Coupled to Massless Scalar Fields
J. Fernando Barbero G., Daniel Gómez Vergel, Eduardo J. S. Villaseñor
The purpose of this paper is to analyze in detail the Hamiltonian formulation for the compact Gowdy models coupled to massless scalar fields as a necessary first step towards their…
