Quasinormal modes of black holes in anti-de Sitter space: a numerical study of the eikonal limit
Jaqueline Morgan, Vitor Cardoso, Alex S. Miranda +2
Using series solutions and time-domain evolutions, we probe the eikonal limit of the gravitational and scalar-field quasinormal modes of large black holes and black branes in anti-…
Gravitational quasinormal modes of AdS black branes in d spacetime dimensions
Jaqueline Morgan, Vitor Cardoso, Alex S. Miranda +2
The AdS/CFT duality has established a mapping between quantities in the bulk AdS black-hole physics and observables in a boundary finite-temperature field theory. Such a relationsh…
Bifurcation of Plasma Balls and Black Holes to Lobed Configurations
Vitor Cardoso, Oscar J. C. Dias
At high energy densities any quantum field theory is expected to have an effective hydrodynamic description. When combined with the gravity/gauge duality an unified picture emerges…
Noncommutative Quantum Cosmology
C. Bastos, O. Bertolami, N. Dias +1
One presents a phase-space noncommutative extension of Quantum Cosmology in the context of a Kantowski-Sachs (KS) minisuperspace model. We obtain the Wheeler-DeWitt (WDW) equation…
Collapsing and static thin massive charged dust shells in a Reissner-Nordström black hole background in higher dimensions
Sijie Gao, José P. S. Lemos
The problem of a spherically symmetric charged thin shell of dust collapsing gravitationally into a charged Reissner-Nordström black hole in spacetime dimensions is studied wit…
One loop superstring effective actions and d=4 supergravity
Filipe Moura
We review our recent work on the existence of a new independent R^4 term, at one loop, in the type IIA and heterotic effective actions, after reduction to four dimensions, besides…
