Ricci flows, wormholes and critical phenomena
Viqar Husain, Sanjeev S. Seahra
We study the evolution of wormhole geometries under Ricci flow using numerical methods. Depending on values of initial data parameters, wormhole throats either pinch off or evolve…
Cosmological perturbations in the DGP braneworld: numeric solution
Antonio Cardoso, Kazuya Koyama, Sanjeev S. Seahra +1
We solve for the behaviour of cosmological perturbations in the Dvali-Gabadadze-Porrati (DGP) braneworld model using a new numerical method. Unlike some other approaches in the lit…
Coupled bulk and brane fields about a de Sitter brane
Antonio Cardoso, Kazuya Koyama, Andrew Mennim +2
We consider the evolution of a bulk scalar field in anti-de Sitter (AdS) spacetime linearly coupled to a scalar field on a de Sitter boundary brane. We present results of a spectra…
Braneworld resonances
Chris Clarkson, Sanjeev S. Seahra
We investigate in detail gravitational waves in an Schwarzschild-anti-de Sitter bulk spacetime surrounded by an Einstein static brane with generic matter content. Such a model prov…
Ringing the Randall-Sundrum braneworld: metastable gravity wave bound states
Sanjeev S. Seahra
In the Randall-Sundrum scenario, our universe is a 4-dimensional `brane' living in a 5-dimensional bulk spacetime. By studying the scattering of bulk gravity waves, we show that th…
