Inflationary perturbation spectrum in extended effective field theory of inflation
Jin Qiao, Guang-Hua Ding, Qiang Wu +2
The effective field theory (EFT) of inflation provides a natural framework to study the new physical effects on primordial perturbations. Recently a healthy extension of the EFT of…
Lifshitz spacetimes, solitons, and generalized BTZ black holes in quantum gravity at a Lifshitz point
Fu-Wen Shu, Kai Lin, Anzhong Wang +1
In this paper, we study static vacuum solutions of quantum gravity at a fixed Lifshitz point in (2+1) dimensions, and present all the diagonal solutions in closed forms in the infr…
High-dimensional Lifshitz-type spacetimes, universal horizons and black holes in Hořava-Lifshitz gravity
Kai Lin, Fu-Wen Shu, Anzhong Wang +1
In this paper, we present all -dimensional static diagonal vacuum solutions of the non-projectable Hořava-Lifshitz gravity in the IR limit, and show that they give rise…
Effects of parity violation on non-gaussianity of primordial gravitational waves in Hořava-Lifshitz gravity
Tao Zhu, Wen Zhao, Yongqing Huang +2
In this paper, we study the effects of parity violation on non-gaussianities of primordial gravitational waves in the framework of Hořava-Lifshitz theory of gravity, in which high-…
General covariant Horava-Lifshitz gravity without projectability condition and its applications to cosmology
Tao Zhu, Fu-Wen Shu, Qiang Wu +1
We consider an extended theory of Horava-Lifshitz gravity with the detailed balance condition softly breaking, but without the projectability condition. With the former, the number…
U(1) symmetry and elimination of spin-0 gravitons in Horava-Lifshitz gravity without the projectability condition
Tao Zhu, Qiang Wu, Anzhong Wang +1
In this paper, we show that the spin-0 gravitons appearing in Horava-Lifshitz gravity without the projectability condition can be eliminated by extending the gauge symmetries of th…
