Comparison between the numerical solutions and the Thomas-Fermi approximation for atomic-molecular Bose-Einstein condensates
Leonardo S. F. Santos, Marcelo O. C. Pires, Davi Giugno
We study the stationary solution of an atomic Bose-Einstein condensate coupled coherently to a molecular condensate with both repulsive and attractive interspecies interactions con…
Quasinormal modes of charged fields around a Reissner-Nordström black hole
Maurício Richartz, Davi Giugno
The quasinormal spectrum of a charged scalar field around a non-extremal Reissner-Nordström black hole, specially in the limit of large electromagnetic interaction, has been compre…
Shedding Some New Lights upon the Stellar Quasi-Normal Modes
Elcio Abdalla, Davi Giugno
In the current paper we present some new data on the issue of quasi-normal modes (QNMs) of uniform, neutron and quark stars. These questions have already been addressed in the lite…
An Extensive Search for Overtones in Schwarzschild Black Holes
E. Abdalla, D. Giugno
In this paper we show that with standard methods it is possible to obtain highly precise results for QNMs. In particular, secondary modes are obtained by numerical integration. We…
Field propagation in de Sitter black holes
C. Molina, D. Giugno, E. Abdalla +1
We present an exhaustive analysis of scalar, electromagnetic and gravitational perturbations in the background of Schwarzchild-de Sitter and Reissner-Nordstrom-de Sitter spacetimes…
