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 ...
Time-varying G in shift-symmetric scalar-tensor theories with a Vainshtein mechanism
shift-symmetric scalar-tensor theories Vainshtein mechanism
2011/10/18
We show that the current bounds on the time variation of the Newton constant G can put severe constraints on many interesting scalar-tensor theories which possess a shift symmetry and a nonminimal mat...
