Anomalias de traço e radiação de Hawking
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2007-03-08)
In the present work we obtain the general form for the anomalous stress-energy tensor for static black holes with spherical symmetry, for the three quantum vacuum states of interest in black holes physics. The particular ...
Tensor energia-momento para modelos de spin-2 massivos
(Universidade Estadual Paulista (Unesp), 2018-12-12)
The objective of this work is to calculate the energy-momentum tensor for the 2'(a1) (DALMAZI, 2013) model and for this it was necessary to learn the fundamental knowledge of the classical theory of relativistic fields, ...
El fluido perfecto como herramienta para la formalización de las variables de estado presión y densidad en la TER
(Universidad Pedagógica NacionalLicenciatura en FísicaFacultad de Ciencia y Tecnología, 2020)
La teoría especial de la relatividad (TER) impone con su primer postulado, que todas las leyes de la física deben ser las misma para cualquier observador inercial, en este sentido, el presente trabajo de grado examina el ...
On the space-time admitting some geometric structures on energy-momentum tensors
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas - Sociedad Colombiana de Matemáticas, 2017-07-01)
This paper presents a study of a general relativistic perfect fluid space-time admitting various types of curvature restrictions on energy-momentum tensors and brings out the conditions for which uids of the space-time are ...

Exploring the physics of the sorkin-johnston state : renormalized stress-energy tensor, hadamard and energy conditions
(Universidad de los AndesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2016)
The non-uniqueness of the vacuum state is one of the most characteristic features of the theory of quantum fields in curved backgrounds. Whereas in Minkowski spacetime the invariance with respect to Poincaré symmetry singles ...
