The role of self-interacting right-handed neutrinos in galactic structure
(IOP Publishing, 2016-04)
It has been shown previously that the DM in galactic halos can be explained by a self-gravitating system of massive keV fermions ('inos') in thermodynamic equilibrium, and predicted the existence of a denser quantum core ...
RELATIVISTIC P-BRANES WITHOUT CONSTRAINTS AND THEIR RELATION TO THE WIGGLY EXTENDED OBJECTS
(Plenum Publ CorpNew York, 1995)
Termodinâmica de buracos negros de Schwarzschild
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2018-05-28)
This dissertation consists of a review about some aspects of Schwarzschild black hole thermodynamics and includes a discussion related to the temporal evolution of the masses of these black holes in a thermodynamic context. ...
Criação de partículas espinoriais ELKO por efeitos gravitacionais
(Universidade Estadual Paulista (Unesp), 2017-02-21)
O campo espinorial ELKO associado às partículas de matéria de spin 1/2 e dimensão de massa 1, construídos em um conjunto completo de autoespinores de helicidade dual do operador conjugação de carga, é um canditado a ...
Scalar field dynamics in a BTZ background with generic boundary conditions
(Springer, 2017-11)
The revisit the dynamics of a massive scalar field in a BTZ background taking into account the lack of global hyperbolicity of the spacetime. We approach this issue using the strategy of Ishibashi and Wald which finds a ...
Free massive particles with total energy E<mc2 in curved spacetimes
(American Physical Soc, 2002-05-10)
We analyze free elementary particles with a rest mass m and total energy E<mc2 in the Rindler wedge, outside Reissner-Nordstrom black holes and in the spacetime of relativistic (and nonrelativistic) stars, and use ...
Hilbert space of curved βγ systems on quadric cones
(Int School Advanced Studies, 2008-08-01)
We clarify the structure of the Hilbert space of curved βγ systems defined by a quadratic constraint. The constraint is studied using intrinsic and BRST methods, and their partition functions are shown to agree. The quantum ...
Predictions from an anisotropic inflationary era
(IOP PUBLISHING LTD, 2008)
This paper investigates the predictions of an inflationary phase starting from a homogeneous and anisotropic universe of the Bianchi I type. After discussing the evolution of the background spacetime, focusing on the number ...
QUASI-TOPOLOGICAL QUANTUM FIELD THEORIES AND Z(2) LATTICE GAUGE THEORIES
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We consider a two-parameter family of Z(2) gauge theories on a lattice discretization T(M) of a three-manifold M and its relation to topological field theories. Familiar models such as the spin-gauge model are curves on a ...
Can entanglement explain black hole entropy?
(Universidade Estadual Paulista (Unesp), 2010-11-10)
When seeking inspiration for a future theory of quantum gravity, studying black holes is a promising ansatz, since they present us with several puzzles at the intersection of quantum theory and gravity. Among these is their ...
