Accelerating BTZ spacetime
Wei Xu, Kun Meng, Liu Zhao
An exact solution of -dimensional Einstein gravity with cosmological constant is studied. The corresponding spacetime is interpreted as an accelerating BTZ spacetime. The pr…

Gauss-Bonnet as effective cosmological constant
Liu Zhao, Kun Meng
It is known that Gauss-Bonnet terms in higher dimensional gravity can produce an effective cosmological constant. We add extra examples to this picture by presenting explicitly two…

Accelerating vacua in Gauss-Bonnet gravity
Wei Xu, Kun Meng, Liu Zhao
Accelerating vacua with maximally symmetric, but not necessarily spherical, sections for Einstein and Gauss-Bonnet gravities in generic dimensions are obtained. The acceleration pa…
