Dynamical Scalar Degree of Freedom in Horava-Lifshitz Gravity
Rong-Gen Cai, Bin Hu, Hong-Bo Zhang
We investigate the linear cosmological perturbations of Hořava-Lifshitz gravity in a FRW universe without any matter. Our results show that a new gauge invariant dynamical scalar m…

Gauss-Bonnet Term on Vacuum Decay
Rong-Gen Cai, Bin Hu, Seoktae Koh
We study the effect of the Gauss-Bonnet term on vacuum decay process in the Coleman-De Luccia formalism. The Gauss-Bonnet term has an exponential coupling with the real scalar fiel…
