Scaling Solutions to 6D Gauged Chiral Supergravity
A. J. Tolley, C. P. Burgess, C. de Rham +1
We construct explicitly time-dependent exact solutions to the field equations of 6D gauged chiral supergravity, compactified to 4D in the presence of up to two 3-branes situated wi…
Mimicking Lambda with a spin-two ghost condensate
Claudia de Rham, Andrew J. Tolley
We propose a simple higher-derivative braneworld gravity model which contains a stable accelerating branch, in the absence of cosmological constant or potential, that can be used t…
Weaker Gravity at Submillimetre Scales in Braneworld Models
Claudia de Rham, Tetsuya Shiromizu, Andrew J. Tolley
Braneworld models typically predict gravity to grow stronger at short distances. In this paper, we consider braneworlds with two types of additional curvature couplings, a Gauss-Bo…
