Vainshtein mechanism in Gauss-Bonnet gravity and Galileon aether
Vainshtein mechanism Gauss-Bonnet gravity Galileon aether
2011/10/18
We derive field equations of Gauss-Bonnet gravity in 4 dimensions after dimensional reduction of the action and demonstrate that in this scenario Vainshtein mechanism operates in the flat spherically ...
Extended Horava gravity and Einstein-aether theory
Extended Horava gravity Einstein-aether
2010/3/19
Einstein-aether theory is general relativity coupled to a dynamical, unit timelike vector. If this vector is restricted in the action to be hypersurface orthogonal, the theory is identical to the IR l...
