Título: | Inhomogeneous Loop Quantum Cosmology: Hybrid Quantization and Approximated solutions |
Autor: | Martín de Blas, Daniel CSIC; Martín-Benito, Mercedes CSIC ORCID; Mena Marugán, Guillermo A. CSIC ORCID | Fecha de publicación: | 2014 | Editor: | Springer Nature | Citación: | Springer Proceedings in Mathematics & Statistics 60: 327 (2014) | Resumen: | We study approximation methods to construct physical solutions for the hybrid quantization of the Gowdy model with linear polarization and a massless scalar field. The loop quantization of the Bianchi I background and the presence of inhomogeneities lead to a very complicated Hamiltonian constraint. Therefore, the extraction of physical predictions calls for the introduction of well justified approximations. We show that, for specific regimes of physical interest, one can approximate the Hamiltonian constraint by a more simple one and obtain its solutions. © Springer-Verlag Berlin Heidelberg 2014 | Descripción: | 5 pags.; Progress in Mathematical Relativity, Gravitation and Cosmology. | Versión del editor: | http://dx.doi.org/10.1007/978-3-642-40157-2__47 | URI: | http://hdl.handle.net/10261/118115 | DOI: | 10.1007/978-3-642-40157-2__47 | Identificadores: | doi: 10.1007/978-3-642-40157-2__47 issn: 2194-1009 |
