Quasinormal modes and stability of the rotating acoustic black hole: numerical analysis

Vitor Cardoso, Jose' P. S. Lemos, Shijun Yoshida

The study of the quasinormal modes (QNMs) of the 2+1 dimensional rotating draining bathtub acoustic black hole, the closest analogue found so far to the Kerr black hole, is perform…

Quantum Holonomies in (2+1)-Dimensional Gravity

J. E. Nelson, R. F. Picken

We describe an approach to the quantization of (2+1)--dimensional gravity with topology R x T^2 and negative cosmological constant, which uses two quantum holonomy matrices satisfy…

Quasinormal modes and classical wave propagation in analogue black holes

Emanuele Berti, Vitor Cardoso, Jose' P. S. Lemos

Many properties of black holes can be studied using acoustic analogues in the laboratory through the propagation of sound waves. We investigate in detail sound wave propagation in…

Newtonian limits of warp drive spacetimes

Jose Natario

We find a class of warp drive spacetimes possessing Newtonian limits, which we then determine. The same method is used to compute Newtonian limits of the Schwarzschild solution and…

Perspectives in Fundamental Physics in Space

Orfeu Bertolami, Clovis Jacinto de Matos, Jean Christophe Grenouilleau +2

We discuss the fundamental principles underlying the current physical theories and the prospects of further improving their knowledge through experiments in space.

Plane symmetric traversable wormholes in an anti-de Sitter background

José P. S. Lemos, Francisco S. N. Lobo

We construct solutions of plane symmetric wormholes in the presence of a negative cosmological constant by matching an interior spacetime to the exterior anti-de Sitter vacuum solu…

Translational Invariance and Noncommutative Field Theories

Orfeu Bertolami

Implications of noncommutative field theories with commutator of the coordinates of the form with nilpotent structure constants are investigated. I…

Highly Damped Quasinormal Modes of Kerr Black Holes: A Complete Numerical Investigation

Emanuele Berti, Vitor Cardoso, Shijun Yoshida

We compute for the first time very highly damped quasinormal modes of the (rotating) Kerr black hole. Our numerical technique is based on a decoupling of the radial and angular equ…
