The Coupling of Shape Dynamics to Matter
Henrique Gomes
Shape Dynamics (SD) is a theory dynamically equivalent to vacuum General Relativity (GR), which has a different set of symmetries. It trades refoliation invariance, present in GR,…
Two formalisms, one renormalized stress-energy tensor
Carlos Barceló, Raúl Carballo, Luis J. Garay
We explicitly compare the structure of the renormalized stress-energy tensor (RSET) of a massless scalar field in a (1+1) curved spacetime as obtained by two different strategies:…
Loop quantum cosmology of the Bianchi I model: complete quantization
M Martín-Benito, L J Garay, G A Mena Marugán +1
We complete the canonical quantization of the vacuum Bianchi I model within the improved dynamics scheme of loop quantum cosmology, characterizing the Hilbert structure of the phys…
The trans-Planckian problem as a guiding principle
Luis C. Barbado, Carlos Barceló, Luis J. Garay +1
We use the avoidance of the trans-Planckian problem of Hawking radiation as a guiding principle in searching for a compelling scenario for the evaporation of black holes or black-h…
